Overview
DATASHEET ISL5216 Four-Channel Programmable Digital Downconverter FN6013 Rev.
3.
00 July 13, 2007 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 AGC loop.
The ISL5216 accepts four channels of 16-bit fixed or up to 14-bit mantissa/3-bit exponent floating point real or complex digitized IF samples which are mixed with local quadrature sinusoids.
Each channel carrier NCO frequency is set independently by the microprocessor.
The output of the mixers are filtered with a CIC and FIR filters, with a variety of decimation options.
Gain adjustment is provided on the filtered signal.
The digital AGC provides a gain adjust range of ...
