Analog Devices AD9920A 12‑Bit CCD Signal Processor Datasheet Rev B
The AD9920A 12‑Bit CCD Signal Processor integrates a complete analog front‑end, a 12‑bit ADC, a programmable timing generator and a 19‑channel vertical driver. It provides up to 24 programmable vertical clock signals, on‑chip GPOs for shutter control, and a precision timing core with ~400 ps resolution at 40.5 MHz.
The device operates from –25 °C to +85 °C, supports multiple power‑supply domains, and includes detailed specifications for digital, analog, timing and vertical driver performance. It is intended for use in digital still‑camera applications where high‑speed, high‑precision CCD readout is required.
