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