Specified at pixel rates of up to 65 MHz, the AD9970 consists of a plete analog front end with analog-to-digital conversion bined with a programmable timing driver. The Precision Timing core allows adjustment of high speed clocks with 240 ps resolution at 65 MHz operation. The AD9970 also contains a reduced range LVDS interface for data outputs. The analog front end includes black level clamping, CDS, VGA, and a 65 MSPS, 14-bit ADC. The timing driver provides the high speed CCD clock drivers for RG, HL, and H1 to H4. Operation is programmed using a 3-wire serial interface. Packaged in a space-saving 5 mm × 5 mm, 32-lead LFCSP_VQ, the AD9970 is specified over an operating temperature range of - 25°C to +85°C.
