DESCRIPTION
The GF9101 is a high performance multirate digital filter
which can be programmed to implement a wide range of
signal processing functions using both symmetrical and
asymmetrical filter structures. It is composed of a 12-tap
FIR filter with internal RAM to hold up to 108 individual
filters. An externally controlled address bus selects one of
the 108 filters in each clock cycle. Pipelined architecture
allows cascading of up to three devices with no additional
hardware.
Two 10-bit input shift registers are provided for multiplexed
filtering applications. The 12-bit coefficients can be
programmed
in
serial,
microprocessor modes. In the high speed parallel mode,
any one of the 108 filters can be reprogrammed in 18 clock
cycles.
