The fido2100 is part of the Innovasic fido® family of real-time communication products. The fido2100 is a managed, 3-port Ethernet switch with support for IEEE-1588 and Device Level Ring (DLR) protocol. The fido2100 enhances the capabilities of Innovasic’s line of Industrial Ethernet products by providing an infrastructure element with low latency, time synchronization and redundancy for any embedded Industrial Ethernet solution.The fido2100 is an IEEE 802.3 standard compliant, Layer 2 switch that is compatible with the IEEE 802.1D standard. It has three ports: two are external ports that function as physical ports of a product and one is an internal port that connects to the host CPU. Each of the three ports has an IEEE 802.3 compliant MAC and the ports are interconnected with each other through full wire speed, non-blocking switching logic. Figure 1 illustrates the top-level blocks of the fido2100 architecture.The pass-through of traffic is handled swiftly by using cut through forwarding to pass traffic to the other external port. This is accomplished without host CPU intervention, which keeps throughput time host interaction to a minimum and keeps pass through delay to a minimum.The fido2100 also has the ability to operate in a DLR configuration, which provides media redundancy amongst its members. Host CPU source code is available to provide the ability for the device to be a DLR participant or a DLR supervisor using the DLR support functions. The fido2100 will default to linear topology operation, and when inserted into a ring, will automatically change to DLR operation as a DLR participant.

The AD736 is a low power, precision, monolithic true rms-to-dc converter. It is laser trimmed to provide a maximum error of ±0.3 mV ± 0.3% of reading with sine wave inputs. Furthermore, it maintains high accuracy while measuring a wide range of input waveforms, including variable duty-cycle pulses and triac (phase)-controlled sine waves. The low cost and small size of this converter make it suitable for upgrading the performance of non-rms precision rectifiers in many applications. Compared to these circuits, the AD736 offers higher accuracy at an equal or lower cost.The AD736 can compute the rms value of both ac and dc input voltages. It can also be operated as an ac-coupled device by adding one external capacitor. In this mode, the AD736 can resolve input signal levels of 100 μV rms or less, despite variations in temperature or supply voltage. High accuracy is also maintained for input waveforms with crest factors of 1 to 3. In addition, crest factors as high as 5 can be measured (introducing only 2.5% additional error) at the 200 mV full-scale input level.The AD736 has its own output buffer amplifier, thereby pro-viding a great deal of design flexibility. Requiring only 200 μA of power supply current, the AD736 is optimized for use in portable multimeters and other battery-powered applications.The AD736 allows the choice of two signal input terminals: a high impedance FET input (1012 Ω) that directly interfaces with High-Z input attenuators and a low impedance input (8 kΩ) that allows the measurement of 300 mV input levels while operating from the minimum power supply voltage of +2.8 V, −3.2 V. The two inputs can be used either single ended or differentially.The AD736 has a 1% reading error bandwidth that exceeds 10 kHz for the input amplitudes from 20 mV rms to 200 mV rms while consuming only 1 mW.The AD736 is available in four performance grades. The AD736J and AD736K grades are rated over the 0°C to +70°C and −20°C to +85°C commercial temperature ranges. The AD736A and AD736B grades are rated over the −40°C to +85°C industrial temperature range. The AD736 is available in three low cost, 8-lead packages: PDIP, SOIC, and CERDIP.PRODUCT HIGHLIGHTS The AD736 is capable of computing the average rectified value, absolute value, or true rms value of various input signals. Only one external component, an averaging capacitor, is required for the AD736 to perform true rms measurement. The low power consumption of 1 mW makes the AD736 suitable for many battery-powered applications. A high input impedance of 1012 Ω eliminates the need for an external buffer when interfacing with input attenuators. A low impedance input is available for those applications that require an input signal up to 300 mV rms operating from low power supply voltages.

The AD8158 is an asynchronous, protocol-agnostic, quad-lane 2:1 switch with a total of 12 differential CML inputs and 12 differential CML outputs. The signal path supports NRZ signaling with data rates up to 6.5 Gbps per lane. Each lane offers programmable receive equalization, programmable output pre-emphasis, programmable output levels, and loss-of-signal detection.The nonblocking switch-core of the AD8158 implements a 2:1 multiplexer and 1:2 demultiplexer per lane and supports independent lane switching through the four select pins, SEL[3:0]. Each port is a four-lane link. Every lane implements an asynchronous path supporting dc to 6.5 Gbps NRZ data, fully independent of other lanes. The AD8158 has low latency and very low lane-to-lane skew.The main application of the AD8158 is to support redundancy on both the backplane and the line interface sides of a serial link. The demultiplexing path implements unicast and bicast capability, allowing the part to support either 1 + 1 or 1:1 redundancy.The AD8158 is also suited for testing high speed serial links because of its ability to duplicate incoming data. In a port-monitoring application, the AD8158 can maintain link-connectivity with a pass-through connection from Port C to Port A while sending a duplicate copy of the data to test equipment on Port B.The rich feature set of the AD8158 can be controlled either through external toggle pins or by setting on-chip control registers through the I2C interface.APPLICATIONS Low cost redundancy switch SONET OC48/SDH16 and lower data rates XAUI/GbE/FC/Infiniband over backplane OIF CEI 6.25 Gbps over backplane Serial data-level shift 4-/8-/12-lane equalizers or redrivers

The ADAU1442 / ADAU1445 / ADAU1446 are enhanced audio processors that allow full flexibility in routing all input and output signals. The SigmaDSP® core features full 28-bit processing (56-bit in double-precision mode), synchronous parameter loading for ensuring filter stability, and 100% code efficiency with the SigmaStudio™ tools. This DSP allows system designers to compensate for the real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of the perceived audio quality through speaker equalization, multiband compression, limiting, and third-party branded algorithms.The flexible audio routing matrix (FARM) allows the user to multiplex inputs from multiple sources running at various sample rates to or from the SigmaDSP core. This drastically reduces the complexity of signal routing and clocking issues in the audio system. FARM includes up to eight stereo asynchronous sample rate converters (depending on the device model), Sony/Philips Digital Interconnect Format (S/PDIF) input and output, and serial (I2S) and time division multiplexing (TDM) I/Os. Any of these inputs can be routed to the SigmaDSP core or to any of the asynchronous sample rate converters (ASRCs). Similarly, any one of the output signals can be taken from the SigmaDSP core or from any of the ASRC outputs. This routing scheme, which can be modified at any time via control registers, allows for maximum system flexibility.The ADAU1442, ADAU1445, and ADAU1446 differ only in ASRC functionality and packaging. The ADAU1442 / ADAU1445 contain 16 channels of ASRCs and are packaged in TQFP packages, whereas the ADAU1446 contains no ASRCs and is packaged in an LQFP. The ADAU1442 can handle nine clock domains, the ADAU1445 can handle three clock domains, and the ADAU1446 can handle one clock domain.The ADAU1442 / ADAU1445 / ADAU1446 can be controlled in one of two operational modes: the settings of the chip can be loaded and dynamically updated through the SPI/I2C® port, or the DSP can self-boot from an external EEPROM in a system with no microcontroller. There is also a bank of multipurpose (MP) pins that can be used as general-purpose digital I/Os or as inputs to the 4-channel auxiliary control ADC.The ADAU1442 / ADAU1445 / ADAU1446 are supported by the SigmaStudio graphical development environment. This software includes audio processing blocks such as FIR and IIR filters, dynamics processors, mixers, low level DSP functions, and third-party algorithms for fast development of custom signal flows.APPLICATIONS Automotive audio processing Head units Navigation systems Rear-seat entertainment systems DSP amplifiers (sound system amplifiers) Commercial audio processing
