The AD6657A is a quad 11-bit, 185 MSPS output data rate IF receiver with integrated noise shaping quantizer.
The AD6657A is an 11‑bit, 200 MSPS quad‑channel intermediate‑frequency receiver designed for high‑dynamic‑range, low‑power telecommunication applications. It integrates four high‑performance ADCs with a selectable noise‑shaping requantizer and provides LVDS digital outputs.
The handbook includes functional block diagrams, detailed electrical specifications, packaging information, and design guidelines for power, grounding, and SPI interfacing, helping designers implement the device in multi‑antenna systems and software‑defined radios.
