The ISL5416 is a four-channel wideband programmable digital downconverter designed for high dynamic range applications such as cellular basestations where the processing of multiple channels is required in a small physical space.
The ISL5416 is a four‑channel digital receiver IC offering a wide dynamic range and flexible programmable features. Each channel includes a front‑end NCO, digital mixer, CIC filter, two FIR filters, AGC, half‑band interpolation and resampling filters. All channels share a common processing clock and support both fixed‑point and floating‑point parallel data inputs.
