AD9289 General Description
The AD9289 is a quad 8-bit, 65 MSPS analogtodigital converter with an onchip trackandhold circuit and is designed for low cost, low power, small size and ease of use. The product operates up to 65 MSPS conversion rate and is optimized for outstanding dynamic performance where a small package size is critical. The ADC requires a single+3V power supply and an LVDS compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications. A separate output power supply pin supports LVDS compatible serial digital output levels.
The ADC automatically multiplies up the sample rate clock for the appropriate LVDS serial data rate. An FCO trigger is provided to signal a new output byte. Power down is supported, and the ADC consumes less than 10mW when enabled. Fabricated on an advanced CMOS process, the AD9289 is
available in a 64-ball mini -BGA package (64 CSP_BGA) specified over the industrial temperature range (40°C to +85°C).
