AD9978A Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD9978A 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.
