DATASHEET ISL5216 FN6013 Rev.3.00 Four-Channel Programmable Digital Downconverter July 13, 2007 The ISL5216 Quad Programmable Digital Downconverter Features (QPDC) is designed for high dynamic range applications Up to 95MSPS Input such as cellular basestations where multiple channel processing is required in a small physical space. The QPDC Four Independently Programmable Downconverter combines into a single package a set of four channels which Channels in a single package include: digital mixers, a quadrature carrier NCO, digital Four Parallel 17-Bit Inputs providing 16-bit fixed or one of filters, a resampling filter, a Cartesian-to-polar coordinate several 17-bit floating point formats converter and an AGC loop. 32-Bit Programmable Carrier NCO with > 115dB SFDR The ISL5216 accepts four channels of 16-bit fixed or up to 110dB FIR Out of Band Attenuation 14-bit mantissa/3-bit exponent floating point real or complex digitized IF samples which are mixed with local quadrature Decimation from 4 to >65536 sinusoids. Each channel carrier NCO frequency is set 24-bit Internal Data Path independently by the microprocessor. The output of the Digital AGC with up to 96dB of Gain Range mixers are filtered with a CIC and FIR filters, with a variety of decimation options. Gain adjustment is provided on the Filter Functions filtered signal. The digital AGC provides a gain adjust range - 1- to 5-Stage CIC Filter of up to 96dB with programmable thresholds and slew rates. - Halfband Decimation and Interpolation FIR Filtering A cartesian to polar coordinate converter provides - Programmable FIR Filtering magnitude and phase outputs. A frequency discriminator is - Resampling FIR Filtering also provided to allow FM demodulation. Selectable outputs include I samples, Q samples, Magnitude, Phase, Cascadable Filtering for Additional Bandwidth Frequency and AGC gain. The output resolution is Four Independent Serial Outputs selectable from 4-bit fixed point to 32-bit floating point. 2.5V Core, 3.3V I/O Operation Output bandwidths in excess of 1MHz are achievable using Pb-Free Plus Anneal Available (RoHS Compliant) a single channel. Wider bandwidths are available by cascading or polyphasing multiple channels.
