The AD9990 is a highly integrated CCD signal processor for digital still camera
The AD9990 is a highly integrated CCD signal processor designed for digital still‑camera applications. It combines a complete analog front end—including a 14‑bit ADC, variable gain amplifier, black‑level clamp, and correlated double sampler—with a programmable timing generator that supports up to 24 vertical clock signals and offers ~488 ps timing resolution.
The device is supplied in a 112‑ball CSP‑BGA package (8 mm × 8 mm, 0.65 mm pitch) and operates from –25 °C to +85 °C. It provides general‑purpose outputs for shutter and system control, on‑chip drivers for external crystal and sync, and is intended for use in digital still‑camera CCDs.
