The AD9970 is a highly integrated CCD signal processor for high speed digital video camera applications. It is specified at pixel rates of up to 65 MHz and features a 1.8 V analog and digital core supply voltage, serial data link, reduced range LVDS outputs, correlated double sampler (CDS) with -3 dB, 0 dB, +3 dB, and +6 dB gain, 6 dB to 42 dB, 10-bit variable gain amplifier (VGA), 14-bit, 65 MHz ADC, black level clamp with variable level control, complete on-chip timing generator, Precision Timing core with 240 ps resolution @ 65 MHz, on-chip 3 V horizontal and RG drivers, and a 5 mm x 5 mm, 32-lead LFCSP_VQ package.
The AD9970 is a highly integrated 14‑bit CCD signal processor designed for high‑speed digital video camera applications. It supports pixel rates up to 65 MHz and includes a complete analog front end, programmable timing driver, and reduced‑range LVDS data outputs. Applications include professional HDTV camcorders, broadcast cameras, industrial high‑speed cameras, and high‑speed data acquisition systems.
Key features include a 1.8 V core supply, correlated double sampler with selectable gain, a 6 dB‑to‑42 dB 10‑bit VGA, on‑chip 3 V horizontal and RG drivers, and a precision timing core with 240 ps resolution. The device is packaged in a 5 mm × 5 mm, 32‑lead LFCSP_VQ and operates from –25 °C to +85 °C.
