AD9971: 12-Bit CCD Signal Processor with Precision Timing

The AD9971 is a highly integrated CCD signal processor for high speed digital video camera applications. Specified at pixel rates of up to 50 MHz, the AD9971 consists of a complete analog front end with analog-to-digital conversion combined with a programmable timing driver. The Precision Timing core allows adjustment of high speed clocks with 310 ps resolution at 50 MHz operation. The AD9971 also contains a reduced range LVDS interface for the data outputs.


The analog front end includes black level clamping, CDS, VGA, and a 50 MSPS, 12-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 6 mm × 6 mm, 40-lead LFCSP_VQ, the AD9971 is specified over an operating temperature range of minus25°C to +85°C.
