14位CCD信号处理器精确定时发生器 14-Bit CCD Signal Processor with Precision Timing Generator
GENERAL DESCRIPTION
The 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.
