TMC2242B General Description
The TMC2242A and TMC2242B are fixed-coefficient linear- 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 rounding. The TMC2242A and TMC2242B accept 12-bit 2's complement 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.
