Description

The AT76C002 FIR filter contains 16 multiplier-accumulators which enable it to implement a 16th order non-symmetrical FIR filter or a 32nd order symmetrical FIR filter, operating at 33 MHz. Furthermore, it can be configured to implement a 64th order filter where the even order coefficients are zero, also running at 33 MHz. The incoming samples are 16 bit coded, the coefficients are 12 bit coded and the internal accuracy is 32 bits.
