The LTC
®
1264 consists of four identical, high speed 2nd
order switched-capacitor filter building blocks designed
for center frequencies up to 250kHz. Each building block,
together with three to five resistors, can provide 2nd order
functions like lowpass, highpass, bandpass and notch.
The center frequency of each 2nd order section is tuned via
an external clock. The clock-to-center frequency ratio is
internally set to 20:1, but it can be modified via external
resistors.
The aliasing performance of the LTC1264 is improved by
double-sampling each 2nd order section. Input signal
frequencies can reach up to twice the clock frequency
before any alias products will be detectable.
For Q
5 and for T
A
< 85°C, the maximum center
frequency is 160kHz. For Q
2, the maximum center
frequency is 250kHz. Up to 8th order filters can be realized
by cascading all four 2nd order sections.
A customized monolithic version of the LTC1264 includ-
ing internal thin film resistors can be obtained.
