The AD9974 is a highly integrated, dual-channel CCD signal processor for high speed digital video camera applications. Each channel includes a 14-bit, 65 MHz analog-to-digital converter and a Correlated double sampler (CDS) with -3 dB, 0 dB, +3 dB and +6 dB gain, as well as a 6 dB to 42 dB, 10-bit variable gain amplifier (VGA). The AD9974 also includes a complete on-chip timing generator with 240 ps resolution @ 65 MHz.
The AD9974 integrates a complete analog front end, 14‑bit 65 MHz ADC, variable gain amplifier, black‑level clamp, and on‑chip timing generator. It provides programmable high‑speed CCD clock drivers and a 3‑wire serial interface for channel configuration. The device is offered in a 100‑lead 9 mm × 9 mm CSP_BGA package and operates from –25 °C to +85 °C.
Typical applications include professional HDTV camcorders, high‑end digital and broadcast cameras, and industrial high‑speed imaging systems. The precision timing core allows clock adjustments with ~240 ps resolution at 65 MHz operation.
