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.

All channels are independently programmable and may be

updated in real time. Each of the four channels can select

any of the four digital input buses. Each of the tuners can

process a W-CDMA channel. Channels may be cascaded or

polyphased for increased bandwidth. Selectable outputs

include I samples, Q samples, and AGC gain. Outputs from

the part are available over the parallel, serial or uP

interfaces.
