Overview
The AD9978BCPZ, produced by Analog Devices Inc., is a highly integrated, dual-channel CCD (Charge-Coupled Device) signal processor designed for high-speed digital video camera applications. Each channel is capable of handling pixel rates up to 65 MHz and includes a complete analog front end with ADC (Analog-to-Digital Converter) conversion. The device features a Precision Timing™ core, which allows for precise adjustment of the correlated double sampler (CDS) and sample-and-hold amplifier (SHA) clocks with a resolution of 240 ps at 65 MHz operation. This makes it ideal for applications requiring high precision and speed in image processing.
