AD6636 is a 150 MSPS, wideband digital downconverter (DDC) from Analog Devices.
The AD6636 is a 150 MSPS wideband digital downconverter designed for IF sampling or oversampled baseband radios. It supports up to six independent processing channels and offers flexible input configurations, including four single‑ended or two LVDS ports.
Key features include three programmable RAM coefficient filters per channel, built‑in self‑test (BIST), synchronous serial I/O, and three 16‑bit parallel output ports that can run at up to 200 MHz. The datasheet provides full electrical, timing, and thermal specifications, as well as programming details for the microport and serial interfaces.
