AD6657 is a quad IF receiver with 11-bit, 200 MSPS output data rate per channel from Analog Devices
The AD6657 is an 11‑bit, 200 MSPS quad‑channel intermediate‑frequency (IF) receiver designed for telecommunication applications such as diversity radio, smart antenna (MIMO) systems, and multimode digital receivers. It integrates four high‑performance ADCs and a noise‑shaping requantizer (NSR) in a compact 10 mm × 10 mm × 1.4 mm CSP‑BGA package.
Key features include low power consumption (1.2 W @ 185 MSPS), 1.8 V LVDS output, programmable integer clock divider, built‑in self‑test (BIST), and flexible power‑down modes. The device supports both NSR‑enabled and NSR‑disabled operation, offering up to 75.5 dBFS SNR in a 22 % bandwidth mode. Detailed specifications, pin configurations, timing diagrams, and design guidelines are provided for system integration.
