Overview
Description
The ISL5216EVAL1 evaluation board is used to evaluate the ISL5216 four-channel programmable digital downconverter.
The ISL5216 quad programmable digital downconverter (QPDC) is designed for high dynamic range applications such as cellular basestations where multiple channel processing is required in a small physical space. The QPDC combines into a single package a set of four channels which include: digital mixers, a quadrature carrier NCO, digital filters, a resampling filter, a cartesian to polar coordinate converter, and an automatic gain control (AGC) loop.
Features
- Up to 95MSPS input
- Four independently programmable downconverter channels in a single package
- Four parallel 17-bit inputs providing 16-bit fixed or one of several 17-bit floating point formats
- 32-bit programmable carrier NCO with >115dB SFDR
- 110dB FIR out of band attenuation
- Decimation from 4 to >65536
- 24-bit internal data path
- Digital AGC with up to 96dB of gain range
- Filter functions
- 1- to 5-stage CIC filter
- Half-band decimation and interpolation FIR filtering
- Programmable FIR filtering
- Resampling FIR filtering
- Cascadable filtering for additional bandwidth
- Four independent serial outputs
- 2.5V core, 3.3V I/O operation
- Pb-free plus anneal available (RoHS compliant)
Applications
- Narrow-band TDMA through IS-95 CDMA digital software radio and basestation receivers
- Wide-band applications: W-CDMA and UMTS digital software radio and basestation receivers
