AD9970: 14-Bit CCD Signal Processor with Precision TimingTM Generator
The AD9970 is a highly integrated CCD signal processor for high speed digital video camera applications. Specified at pixel rates of up to 65 MHz, the AD9970 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 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.
