The ADAU1452/ADAU1451/ADAU1450 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms that can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The restructured digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency.The 1.2 V, 32-bit DSP core can run at frequencies of up to 294.912 MHz and execute up to 6144 instructions per sample at the standard sample rate of 48 kHz. However, in addition to industry-standard rates, a wide range of sample rates are available. The integer PLL and flexible clock generator hardware can generate up to 15 audio sample rates simultaneously. These clock generators, along with the on-board asynchronous sample rate converters (ASRCs) and a flexible hardware audio routing matrix, make the ADAU1452/ADAU1451/ADAU1450 ideal audio hubs that greatly simplify the design of complex multirate audio systems.The ADAU1452/ADAU1451/ADAU1450 interface with a wide range of analog-to-digital converters (ADCs), digital-to-analog converters (DACs), digital audio devices, amplifiers, and control circuitry, due to their highly configurable serial ports, S/PDIF interfaces (on the ADAU1452 and ADAU1451), and multipurpose input/output pins. The devices can also directly interface with pulse density modulation (PDM) output microelectromechanical (MEMS) microphones, due to integrated decimation filters specifically designed for that purpose.Independent slave and master I2C/serial peripheral interface (SPI) control ports allow the ADAU1452/ADAU1451/ADAU1450 not only to be programmed and configured by an external master device, but also to act as masters that can program and configure external slave devices directly. This flexibility, combined with self boot functionality, enables the design of standalone systems that do not require any external input to operate.The power efficient DSP core executes full programs, consumes only a few hundred milliwatts (mW) of power, and can run at a maximum program load while consuming less than a watt, even in worst case temperatures exceeding 100°C. This relatively low power consumption and small footprint make the ADAU1452/ ADAU1451/ADAU1450 ideal replacements for large, general-purpose DSPs that consume more power at the same processing load.Differences between the ADAU1452, ADAU1451, and ADAU1450The five variants of this device are differentiated by memory, DSP core frequency, availability of S/PDIF interfaces, ASRC configuration, and temperature range.Because the ADAU1450 does not contain an S/PDIF receiver or transmitter, the SPDIFIN and SPDIFOUT pins are nonfunctional. Additionally, the settings of any registers related to the S/PDIF input or output in the ADAU1450 do not have any effect on the operation of the device.Because the ADAU1450 does not contain ASRCs, the settings of any registers related to the ASRCs in the ADAU1450 do not have any effect on the operation of the device.Applications Automotive audio processing Head units Navigation systems Rear seat entertainment systems DSP amplifiers (sound system amplifiers) Commercial and professional audio processing Consumer audio processing

The ADV7186 is a high performance, single chip, multiformat video decoder and processor with integrated LVDS Tx and LVDS Rx. The ADV7186 analog front end comprises single high speed, 10-bit ADC that digitizes the analog video signal. The ADV7186 analog front end supports input resolutions up to SVGA (800 × 600 at 60 Hz). The ADV7186 has 48 pixel pins, of which 24 are inputs and 24 are outputs.The ADV7186BBCZ-T contains features identical to the ADV7186BBCZ apart from having a TCON (LCD timing control) output in place of the LVDS Tx output and not supporting an LVDS Rx.The ADV7186BBCZ-TL is a reduced function version of the ADV7186BBCZ-T and does not support external SDRAM. All other functionality is identical to that of the ADV7186BBCZ-T.The multiformat decoder contains a standard definition processor (SDP) supporting the conversion of PAL, NTSC, and SECAM standards in the form of a composite or an S-Video input signal into a digital ITU-R BT.656 format.The ADV7186 contains one main component processor (CP) that processes YPbPr and RGB component formats, including RGB graphics. The ADV7186 analog front end supports the decoding of these RGB/YPbPr video signals into a digital YCbCr or RGB pixel output stream. The support for component video includes 525i, 525p, 625i, 625p, 720p, and 1080i standards while QVGA to SVGA graphic rates are supported.The CP core can also process video with resolutions up to WXGA from the input pixel pins or LVDS Rx.The video signal processor can perform edge-adaptive intrafield de-interlacing, ensuring excellent performance on low angle edges as well as antiflickering filtering. The video signal processor allows scaling between common video resolutions, enabling up to WXGA output (the output frame rate is always equal to the input field/frame rate). ACE offers improved visual detail. Flip/mirror capability allows for compensation of different camera mounting orientations.An independent BT.656 channel allows access to the output of the SD and CP cores. Simultaneously, the output pixel bus or LVDS Tx can drive out video data that has been received via the input pixel bus or the LVDS Rx bus. In the case of the ADV7186BBCZ only, the pins used for the BT.656 channel are shared with the external memory interface. In the case of the ADV7186BBCZ-T and ADV7186BBCZ-TL, the pins used for the independent BT.656 channel are shared with both the external memory interface and the TCON[10:0] pins, leaving it to the user to select the preferred option.The ADV7186 can accept up to two layers of overlay on the main picture. The sources of this overlay can be the TTL/LVDS Rx and/or the EEPROM bitmap or the low cost overlay. These layers can be overlaid on the input video stream using alpha blending and chroma keying.In addition to the full overlay functionality, the ADV7186 supports a low cost overlay function that requires no external memory. This feature allows overlay on a predefined section of the display using one foreground and one background color, allowing a warning or information banner to be displayed over the viewed video.The LCD controller function includes TCON signals enabling the ADV7186BBCZ-T and ADV7186BBCZ-TL only to drive glass-only panels. PWM backlight control enables a programmable dimming ratio. To compensate for nonlinearity in the video system, the ADV7186 allows a 32-point gamma correction curve to be applied independently on each output channel (RGB or YCbCr).Where boot time is critical, the ADV7186 has a hardware self-configurable fastboot feature, enabling video to be displayed directly after power-up. Bitmaps stored in the EEPROM can also be loaded and displayed on power-up.The ADV7186W models are automotive qualified.APPLICATIONS Navigation radios and infotainment head units Central console and rear seat monitors Parking guide and ADAS vision systems Pico and mini projectors Industrial monitors and displays

The ADV8005 is a multiple input video signal processor that can deinterlace and scale standard definition (SD), enhanced definition (ED), or high definition (HD) video data to ultra HD formats; generate a bitmap on-screen display (OSD); and output the video with OSD overlaid on two High-Definition Multimedia Interface (HDMI®) transmitters and a video encoder.The 60-bit TTL video port can be used to input video to the ADV8005 in a number of ways: using the 48-bit TTL pixel port, using the 24-bit external OSD TTL pixel port, or from a device with an HDMI transmitter such as the ADV7850. The ADV8005 supports many of the formats outlined in the CEA-861-F and VESA specifications, as well as several other widely used timing formats.The ADV8005 features primary and secondary video scalers that enable simultaneous output of multiple different resolutions. The primary video scaler can upscale to 4k × 2k modes. The secondary video scaler can upscale to 1080p or UXGA graphics. 4k × 2k downscaling is performed using the secondary video scaler, leaving the primary video scaler available for other video processing.The ADV8005 primary video scaler can perform high performance, motion adaptive interlaced to progressive conversion on SD and HD content. Additional functionality has also been added to ADV8005 to facilitate upscaling and downscaling to VESA formats with pixel clock frequencies below 300 MHz.Detail enhancement and image enhancing techniques such as random, mosquito, and block noise reduction allow improved final image quality. The frame rate converter of the ADV8005 allows the conversion between common frame rates with support to output two different frame rates simultaneously under certain conditions. The VSP can do aspect ratio conversion, CUE correction, crop output image.The ADV8005 can accept OSD video from an external OSD source on one of its inputs and it can internally generate a high quality, bitmap-based OSD. The internal OSD is highly flexible and allows the system designer to easily incorporate features like scrolling text and animation in various color depths up to 24-bit true color with alpha blending, such as RGB565, ARGB4444 and ARGB8888.Analog Devices, Inc., provides an OSD development tool (Blimp) to assist in the design, debug, and emulation of the OSD prior to integration with the system application. When the design is complete, the OSD development tool automatically generates code to which system application programming interfaces (APIs) can be added before integration with the system application and an OSD design resource, which must be downloaded to an external SPI flash memory.Video can be output from the ADV8005 using one or both of the HDMI transmitters and/or the six-DAC SD/HD video encoder. The six 12-bit NSV® video DACs allow composite (CVBS), S-Video (Y/C), and component (YPrPb) analog outputs in standard, enhanced, and high definition video formats. Oversampling of 216 MHz (SD and ED) and 297 MHz (HD) removes the requirement for external output filtering. Rovi® and non-Rovi variants of the ADV8005 are available.Both of the HDMI transmitters on the ADV8005 support 4k × 2k and all mandatory and many optional 3D video resolutions. Each transmitter features an audio return channel receiver (ARC). The ADV8005 can receive up to eight channels of I2S, S/PDIF, direct stream digital (DSD), and high bit rate (HBR) audio passed from either the serial video Rx or from the externally available audio input pins.The ADV8005 supports the I2C protocol for communication with the system microcontroller.

The AD637 is a complete, high accuracy, rms-to-dc converter that computes the true rms value of any complex waveform. It offers performance that is unprecedented in integrated circuit rms-to-dc converters and comparable to discrete and modular techniques in accuracy, bandwidth, and dynamic range. The AD637 computes the true root mean square, mean square, or absolute value of any complex ac (or ac plus dc) input waveform and gives an equivalent dc output voltage. The true rms value of a waveform is more useful than an average rectified signal because it relates directly to the power of the signal. The rms value of a statistical signal relates to the standard deviation of the signal.Superior crest factor compensation permits measurements of signals with crest factors of up to 10 with less than 1% additional error. The wide bandwidth of the AD637 permits the measurement of signals up to 600 kHz with inputs of 200 mV rms and up to 8 MHz when the input levels are above 1 V rms.Direct dB value of the rms output with a range of 60 dB is available on a separate pin. An externally programmed reference current allows the user to select the 0 dB reference voltage to correspond to any level between 0.1 V and 2.0 V rms.A chip select connection on the AD637 permits the user to decrease the supply current from 2.2 mA to 350 µA during periods when the rms function is not in use. This feature facilitates the addition of precision rms measurement to remote or handheld applications where minimum power consumption is critical. In addition, when the AD637 is powered down, the output goes to a high impedance state. This allows several AD637s to be tied together to form a wideband true rms multiplexer.The input circuitry of the AD637 is protected from overload voltages in excess of the supply levels. The inputs are not damaged by input signals if the supply voltages are lost.The AD637 is laser wafer trimmed to achieve rated performance without external trimming. The only external component required is a capacitor that sets the averaging period. The value of this capacitor also determines low frequency accuracy, ripple level, and settling time.The on-chip buffer amplifier is used either as an input buffer or in an active filter configuration. The filter can be used to reduce the amount of ac ripple, thereby increasing accuracy.The AD637 is available in accuracy Grade J and Grade K for commercial temperature range (0°C to 70°C) applications, accuracy Grade A and Grade B for industrial range (−40°C to +85°C) applications, and accuracy Grade S rated over the −55°C to +125°C temperature range. All versions are available in hermetically sealed, 14-lead SBDIP, 14-lead CERDIP, and 16-lead SOIC_W packages.
