Table 3. FIR2 Filter Coefficients

binary multiples of clock cycles relative to each

other, going from slowest to the fastest, but

because of the internal data buffering the filter

actually takes one more filter output word to

settle than a strict analysis of the filter

coefficients would imply. The filter settles to

full accuracy to a input step in 57 output words.

Tables 2, 3 and 4 list the filter coefficients for

the three FIR filter stages.

The CS5322 digital filter consumes only 11

milliwatt power although it consist of

approximately 76,000 transistors. An analog

filter of comparable complexity would consist of

over 233,000 reactive elements.
