Each channel is specified at pixel rates of up to 65 MHz. The AD9974 consists of a complete analog front end (AFE) with analog-to-digital conversion, combined with a programmable timing driver. The Precision Timing™ core allows adjustment of high speed clocks with approximately 240 ps resolution at 65 MHz operation. Each AFE includes black level clamping, CDS, VGA, and a 65 MSPS, 14-bit ADC. The timing driver provides the high speed CCD clock drivers for the RG_A, RG_B, H1_A to H4_A, and H1_B to H4_B outputs. A 3-wire serial interface is used to program each channel of the AD9974. Available in a space-saving, 9 mm × 9 mm, C...
