LTC1264CSW#PBF

LTC1264 is a high speed, quad universal filter building block. It consists of four identical, high speed 2nd order switched-capacitor filter building blocks designed for centre frequencies up to 250KHz. Each building block, together with three to five resistors, can provide 2nd order functions like lowpass, high pass, bandpass and notch. The centre frequency of each 2nd order section is tuned via an external clock. The clock-to-centre frequency ratio is internally set to 20:1, but it can be modified via external resistors. The aliasing performance of the device is improved by double-sampling each 2nd order section. Input signal frequencies can reach upto twice the clock frequency before any alias products will be detectable. It is widely used in application such as digital communications, spread spectrum communications, spectral analysis, loran receivers, instrumentation etc.
