Analog Devices Inc. launched the flagship device in a family of analog front ends (AFEs) for high-definition (HD) image/video processing applications with a low-voltage differential signaling interface that is said to boost signal conversion performance by 30 percent.

The AD9970 AFE consists of a 14-bit analog-to-digital converter (ADC) operating at 155mW at 65Msamples/s, a variable gain amplifier (VGA) and correlated double sampler (CDS), in a 5-by-5mm package.

A programmable timing driver, dubbed Precision Timing, further boosts performance by enabling precise and localized control of high-speed charge-coupled device (CCD) clock signals, said Stuart Boyd, ADI's product line director, high-speed signal processing business.

Designed for consumer imaging products such as camcorders and digital still cameras, the AD9970 serves as a complete AFE. "The performance of ADI's AD9970 AFE is necessary to capture HD content and enable the advanced capabilities that consumers are seeking in today's HD camcorders," Boyd said.

The AD9970 is also one of the first AFEs on the market to use a low-voltage differential signaling (LVDS) interface for HD imaging equipment, Boyd said.

The AD9970 AFE is available for $10.74 per unit in 1,000-piece quantities in a 5-by-5mm LFCSP. It is specified over an operating temperature range of -250C to 850C.
