The AD9880 offers designers the flexibility of an analog interface and High-Definition Multimedia Interface (HDMI™) receiver integrated on a single chip. Also included is support for High bandwidth Digital Content Protection (HDCP).ANALOG INTERFACEThe AD9880 is a complete 8-bit 150 MSPS monolithic analog interface optimized for capturing Component Video (YPbPr) and RGB graphics signals. Its 150 MSPS encode rate capability and full power analog bandwidth of 300 MHz supports all HDTV formats (up to 1080p) and FPD resolutions up to SXGA (1280 × 1024 at 75 Hz).The analog interface includes a 150 MHz triple ADC with internal 1.25V reference, a Phase Locked Loop (PLL), and programmable gain, offset, and clamp control. The user provides only 1.8V and 3.3V power supply, analog input, and Hsync. Three-state CMOS outputs may be powered from 1.8V to 3.3V. The AD9880’s on-chip PLL generates a pixel clock from Hsync. Pixel clock output frequencies range from 12 MHz to 150 MHz. PLL clock jitter is typically less than 500 ps p-p at 150 MHz. The AD9880 also offers full sync processing for composite sync and Sync-on-Green (SOG) applications.DIGITAL INTERFACEThe AD9880 contains a HDMI v1.1 compatible receiver and supports all HDTV formats (up to 1080p) and display resolutions up to SXGA (1280 × 1024 at 75 Hz). The receiver features an intra-pair skew tolerance of up to one full clock cycle. With the inclusion of HDCP, displays may now receive encrypted video content. The AD9880 allows for authentication of a video receiver, decryption of encoded data at the receiver, and renewability of that authentication during transmission as specified by the HDCP v1.1 protocol.Fabricated in an advanced CMOS process, the AD9880 is provided in a space-saving 100-lead LQFP surface-mount Pb-free plastic package and is specified over the 0 ºC to 70 ºC temperature range.APPLICATIONS Advanced TV HDTV Projectors LCD Monitor

The AD9888 is a complete 8-bit, 170 MSPS, monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations. Its 170 MSPS encode rate capability and full-power analog bandwidth of 500 MHz supports resolutions of up to 1600 × 1200 (UXGA) at 75 Hz.For ease of design and to minimize cost, the AD9888 is a fully integrated interface solution for flat panel displays. The AD9888 includes an analog interface that has a 170 MHz triple ADC with an internal 1.25 V reference phase-locked loop (PLL) to generate a pixel clock from HSYNC and COAST; midscale clamping; and programmable gain, offset, and clamp controls. The user provides only a 3.3 V power supply, analog input, and HSYNC and COAST signals. Three-state CMOS outputs can be powered from 2.5 V to 3.3 V.The on-chip PLL of the AD9888 generates a pixel clock from the HSYNC and COAST inputs. Pixel clock output frequencies range from 10 MHz to 170 MHz. PLL clock jitter is typically less than 450 ps p-p at 170 MSPS. When the COAST signal is presented, the PLL maintains its output frequency in the absence of HSYNC. A sampling phase adjustment is provided. Data, HSYNC, and clock output phase relationships are maintained. The PLL can be disabled, and an external clock input can be provided as the pixel clock. The AD9888 also offers full sync processing for composite sync and sync-on-green applications.A CLAMP signal is generated internally or can be provided by the user through the CLAMP input pin. This device is fully programmable via a 2-wire serial port.Fabricated in an advanced CMOS process, the AD9888 is provided in a space-saving, 128-lead, MQFP, surface-mount, plastic package and is specified over the 0°C to 70°C temperature range.

110MHz ANALOG INTFCE FOR SGA FPD

The LT3478/LT3478-1 are 4.5A step-up DC/DC converters designed to drive LEDs with a constant current over a wide programmable range. Series connection of the LEDs provides identical LED currents for uniform brightness without the need for ballast resistors and expensive factory calibration.The LT3478-1 reduces external component count and cost by integrating the LED current sense resistor. The LT3478 uses an external sense resistor to extend the maximum programmable LED current beyond 1A and also to achieve greater accuracy when programming low LED currents. Operating frequency can be set with an external resistor from 200kHz up to 2.25MHz. Unique circuitry allows a PWM dimming range up to 3000:1 while maintaining constant LED color. The LT3478/LT3478-1 are ideal for high power LED driver applications such as automotive TFT LCD backlights, courtesy lighting and heads-up displays. One of two CTRL pins can be used to program maximum LED current. The other CTRL pin can be used to program a reduction in maximum LED current vs temperature to maximize LED usage and improve reliability.Additional features include inrush current protection, programmable open LED protection and programmable soft-start. Each part is available in a 16-pin thermally enhanced TSSOP Package.Applications High Power LED Driver Automotive Lighting

Demonstration circuit 976 is a Quadruple High Power LED Driver in Buck Mode featuring the LT3476EUHF. The LT3476 is a quad output, multitopology DC/DC converter designed to operate as a current source for driving high current LEDs. Each of the four regulators on the demo circuit is independently operated. The VIN power supply for the IC ranges from 2.8V to 16V. The PVIN power supply for the buck regulators ranges up to 33V. On the demo circuit, the default current for each output channel is 350mA but it can be adjusted up to 1.05A via resistor dividers at the VADJ pins. The output current should not exceed the rated current of the LEDs used. If 1W LEDs, such as the Lumileds Luxeon LEDs, are used, 350mA current is the maximum. 1A output current is reserved for 3W LEDs, such as Luxeon III. The input voltage is limited by the CAP pin overvoltage protection threshold. As a result, each channel of the demo circuit can drive up to 27V total LED voltage.
