Features  
• TMC2242A and TMC2242B are pin-compatible with  
TMC2242  
• Single +5 Volt power supply operation  
• Small 44-Lead PLCC and 44-Lead MQFP  
• User selectable interpolate gain, -6 dB or 0 dB (2242B)  
• 30, 40 and 60 MHz speed grades  
• User selectable 2:1 decimation, 1:2 interpolation, and  
equal-rate filter modes  
Applications  
• Low-cost video filtering  
• Chrominance bandwidth limiter  
• Simple, inexpensive video D/A post-filters  
• Reduced cost and complexity for A/D anti-aliasing filters  
• High-performance digital low-pass filters  
• Digital waveform reconstruction post-filtering  
• Telecommunications  
• Passband ripple < ±0.01 dB  
• Stopband rejection 59.4 dB from 0.28 to 0.50 x f  
s
• Cascading two TMC2242A or TMC2242B meets  
CCIR 601 low-pass filter requirement  
• Dedicated 12-bit 2's complement input data port and  
16-bit output data port with user-selectable rounding from  
9 to 16 bits  
• Direct digital synthesis  
• Radar  
• Two's complement or offset binary output format  
• Built-in limiter prevents overflow  
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.
