Overview
Description
The ISL5416EVAL1 evaluation board is used to evaluate the ISL5416 wideband programmable digital downconverter (WPDC).
The ISL5416 four-channel wideband programmable digital downconverter (WPDC) is designed for high dynamic range applications such as cellular basestations where the processing of multiple channels is required in a small physical space. The WPDC combines four channels in a single package, each including an NCO, a digital mixer, digital filters, an AGC, and a resampling filter.
