双通道， 14位高清图像信号处理器，采用Precision Timing内核 Dual-Channel, 14-Bit HD Image Signal Processor with Precision Timing Core
GENERAL DESCRIPTION
The is a highly integrated, dual-channel, charge coupled device CCD signal processor for high speed digital video camera applications. Each channel is specified at pixel rates of up to 75 MHz and consists of a complete analog front end AFE with ADC conversion. The Precision Timing™ core allows adjustment of the correlated double sampler CDS and sample-and-hold amplifier SHA clocks with 210 ps resolution at 75 MHz operation. The AD9978A also contains a reduced range low voltage differential signaling LVDS interface for the dual-channel data outputs.
