ISL5216KI-1規(guī)格書詳情

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.
