Description
AI
The AD9229 is a 50 or 65 MSPS quad 12-bit, analog–to–digital converter with serial LVDS outputs. An on–chip track–and–hold circuit is designed for low cost, low power, small size and ease of use. The product operates up to a 65 MSPS conversion rate and is optimized for outstanding dynamic performance where a small package size is critical.The ADC requires a single +3 V power supply. 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. This data clock output (DCO) provides operation up to 390 MHz and supports double-data rate operation (DDR). An MSB trigger or Frame clock is also provided to signal a new output byte. Power down is supported, and the ADC consumes 3 mW when enabled.Fabricated on an advanced CMOS process, the AD9229 is available in a 48-pin chip scale 7 mm x 7 mm package (48-LFCSP) specified over the industrial temperature range (–40°C to +85°C).ApplicationsDigital beam forming systems for ultrasoundWireless and wired broadband communicationsCommunication test equipment
