The AD6655 is a communications diversity receiver that integrates dual-channel ADCs, digital downconverters, and digital frequency synthesizers for flexible and versatile receiver implementations.
The AD6655 is a mixed‑signal intermediate‑frequency receiver that integrates dual 14‑bit ADCs (80‑150 MSPS) and a wideband digital down‑converter. It supports 1.8 V analog supply operation and offers flexible output modes including CMOS and LVDS.
Designed for communications applications such as diversity radio systems, smart antennas and software‑defined radios, the device is offered in a 64‑lead LFCSP and operates over an industrial temperature range of –40 °C to +85 °C.
