Four-Channel Wideband Programmable

DownConverter

Features

• Up to 95MSPS Input

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.

• Four Parallel 16-bit Fixed or 17-bit Floating Point Inputs

• Programmable RF Attenuator/VGA Control

• 32-Bit Programmable Carrier NCO with > 110dB SFDR

• 20-bit Internal Data Path

• Filter Functions

- Multi-Stage Cascaded-Integrator-Comb (CIC) 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.

- Two programmable FIR Filters (first up to 32-taps,

second up to 64-taps)

- Half Band Interpolation Filter

- Resampling FIR Filter

• Overall decimation from 1 to >4096

• Digital AGC with up to 96dB of Gain Range

• Up to Four Independent 16-bit Parallel Outputs

• Serial Output Option
