AD9974 is a highly integrated dual-channel, charge-coupled device (CCD) signal processor for high speed digital video acquisition. It features a 14-bit, 65 MHz analog-to-digital converter (ADC), a 10-bit variable gain amplifier (VGA), a black level clamp, and a complete on-chip timing generator with 240 ps resolution @ 65 MHz.
The AD9974 is a highly integrated dual‑channel charge‑coupled device (CCD) signal processor designed for high‑speed digital video camera applications. Each channel supports pixel rates up to 65 MHz and includes a complete analog front end with black‑level clamp, correlated double sampler, variable‑gain amplifier and a 14‑bit, 65 MSPS ADC.
The device features a Precision Timing™ core with ~240 ps resolution, on‑chip 3 V horizontal and reset‑gate drivers, and a 3‑wire serial interface for programming. It is supplied in a 100‑lead 9 mm × 9 mm CSP‑BGA package and operates from –25 °C to +85 °C.
