ODES OF OPERATIOU
W
The parallel combination of R5 and R6 should be kept
below 5k.
Please refer to the Operating Limits paragraph under Appli-
cations Information for a guide to the use of capacitor C
C
.
Mode 3
In Mode 3, the ratio of the external clock frequency to the
center frequency of each 2nd order section can be ad-
justed above or below the part’s nominal ratio. Figure 5
illustrates Mode 3, the classical state variable configura-
tion, providing highpass, bandpass and lowpass 2nd
order filter functions. Mode 3 is slower than Mode 1. Mode
3 can be used to make high order all-pole bandpass,
lowpass and highpass filters.
Please refer to the Operating Limits paragraph under Appli-
cations Information for a guide to the use of capacitor C
C
.
Mode 2
Mode 2 is a combination of Mode 1 and Mode 3, shown in
Figure 6. With Mode 2, the clock-to-center frequency ratio,
f
CLK
/f
O
, is always less than the part’s nominal ratio. The
advantage of Mode 2 is that it provides less sensitivity to
resistor tolerances than does Mode 3. Mode 2 has a
highpass-notch output where the notch frequency
depends solely on the clock frequency and is therefore
less than the center frequency, f
O
.
