Description

The TMC2242A and TMC2242B are fixed-coefficient lin-
ear-phase half-band (low-pass) digital filters. They can be
used to halve or double the sampling rate of a digital signal.
When used as a decimating post-filter with a double-speed
oversampling A/D converter, they greatly reduce the cost and
complexity of anti-aliasing filters required ahead of the A/D
converter. When used as an interpolating pre-filter with a
double-speed oversampling D/A converter, the TMC2242A
and TMC2242B significantly reduce the design complexity
and production cost of reconstruction filters used on D/A
outputs.
The TMC2242A and TMC2242B user selects the mode of
operation (decimate, interpolate, or equal-rate) and round-
ing. The TMC2242A and TMC2242B accept 12-bit 2's com-
plement data at up to 60 MHz and output saturated
(overflow-protected) 2's complement or offset binary data
rounded to from 9 to 16 bits. Within the speed grade I/O
limit, the output sample rate may be 1/2, 1, or 2 times the
input sample rate.
