The AD6653 is an RF receiver produced by Analog Devices that supports 1.8V to 3.3V CMOS output power or 1.8V LVDS output power, with sample rates up to 150 MSPS and IF sampling frequencies up to 450 MHz.
The AD6653 is a mixed‑signal intermediate‑frequency (IF) receiver that integrates dual 12‑bit ADCs operating at up to 150 MSPS and a wide‑band digital down‑converter. It supports flexible analog input ranges, multiple output modes (CMOS and LVDS), and includes built‑in voltage reference, duty‑cycle stabilizer, and programmable threshold detection for low‑latency over‑range protection.
The document provides detailed electrical specifications, pin configurations, functional block diagrams, and design guidelines for communications applications such as diversity radio systems, smart antennas, and software‑defined radios. It also lists power consumption, thermal characteristics, and recommended operating conditions for industrial temperature ranges.
