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 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 up to 96dB with programmable thresholds and slew rates.
A cartesian to polar coordinate converter provides
magnitude and phase outputs. A frequency discriminator is
also provided to allow FM demodulation. Selectable outputs
include I samples, Q samples, Magnitude, Phase, Frequency
and AGC gain. The output resolution is selectable from 4-bit
fixed point to 32-bit floating point.
Output bandwidths in excess of 1MHz are achievable using
a single channel. Wider bandwidths are available by
cascading or polyphasing multiple channels.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
