ADV7402/ADV7400 Multiformat Video Decoders for Advanced TV is the first to integrate 12-bit quality video decoding with high speed graphics and high definition video digitization. With 12 analog input channels, the ADV7402 enables system designers to choose one part to route or convert multiple analog video inputs into industry-standard or proprietary output interfaces. Supporting single data rate (SDR) and double data rate (DDR) output modes, interfacing to popular scalers, MPEG A/V CODECs, and graphics processors is easily achieved. Using the on-board 3 x 3 conversion matrix, digital or analog RGB inputs can be converted to any color space. The ADV7402 is suitable for a wide range of domestic and worldwide consumer electronics designs, and is ideal for home theater projectors or direct view and rear projection HDTVs, where two or more chips (decoder and ADC) can be replaced with one ADV7402 IC. For cost-sensitive applications, the ADV7400 provides designers with high performance 10-bit ADCs and an 8-bit accurate output interface.

AD7150 Capacitance Converter for Proximity Sensing Addresses Power and Sensitivity Requirements

The AD6600/AD6620 Diversity Receiver chipset is a highly integrated chipset that reduces the size and cost of base station receivers. It incorporates Automatic Gain Control, Received Signal Strength Indicator, high-resolution Numerically Controlled Oscillator, and digital filtering on-chip. The chipset can address various air interface standards, including GSM, CDMA, IS136, and PHS, as well as proprietary modulation schemes for paging systems and wireless fixed access receivers.

This application note introduces how to interface AD7276 high speed data converter with Blackfin® processor. It also provides an example code to demonstrate how to program the Blackfin processor's serial ports (SPI and SPORT) to receive data from AD7276 device in both core access and DMA access modes. Power-down mechanism between ADC conversions in DMA mode is also introduced. The entire reference design is implemented on ADSP- BF535 EZ-KIT Lite™ board.

This PDF document introduces Analog Devices' optical and high speed networking integrated circuits (ICs), which solve a variety of challenges faced by designers of datacom and telecom systems, optical modules, and subsystems. Analog Devices' products are suitable for a wide range of networking applications, including O/E/O conversion, clock recovery, backplane transmission, monitoring and control of optical power, power management, and clock generation and distribution. These high-performance ICs are designed to help users solve their networking problems simply and quickly, without compromising performance.

This application note describes a low-cost, high-accuracy watt-hour meter based on the AD7751. The meter described is intended for use in single-phase, two-wire distribution systems. However, the design can easily be adapted to suit specific regional requirements, e.g., in the United States power is usually distributed to resi- dential customers as single-phase, three-wire. The AD7751 is a low-cost, single-chip solution for elec- trical energy measurement. The most distinctive feature of the AD7751 is that it continuously monitors the phase and neutral (return) currents. A FAULT condition occurs if the two currents differ by more than 12.5%. Power cal- culation will be based on the larger of the two currents. The meter calculates power correctly even if one of the two wires does not carry any current. AD7751 provides an effective way to combat any attempt to return the current through earth, a very simple yet effective way of meter tampering. The AD7751 is comprised of two ADCs, reference circuit, and all the signal processing necessary for the calculation of real (active) power. The AD7751 also includes direct drive capability for electrome- chanical counters (i.e., the energy register) and has a high-frequency pulse output for calibration and com- munications purposes. This application note should be used in co-operation with the AD7751 and other related devices to construct an electrical energy measurement system.
