AD6654 Rev. 0 is a 14-bit, 92.16 MSPS, 4-/6-channel wideband IF to baseband receiver. It features high signal-to-noise ratio, integrated ADC, programmable filters, and built-in self-test capability.
The AD6654 is a mixed‑signal IF‑to‑baseband receiver that combines a 14‑bit, 92.16 MSPS analog‑to‑digital converter with a 4‑ or 6‑channel digital down‑converter. It is intended for wideband wireless standards such as CDMA2000, UMTS, TD‑SCDMA, and WiMAX, and can be used in radios, software‑defined radios, and test equipment.
Key features include an internal 2.4 V reference, differential track‑and‑hold input, programmable FIR and half‑band filters, three 16‑bit parallel output ports, and serial interfaces (SPORT, SPI, SSR). The datasheet provides detailed specifications, timing diagrams, electrical characteristics, and an ordering guide for both 4‑channel and 6‑channel versions.
