Programmable low-pass filter

6 March 2013 Analogue, Mixed Signal, LSI

The HMC1023LP5E is a 6th order, programmable bandwidth, fully calibrated, dual low-pass filter from Hittite. It features programmable 0 or 10 dB gain and supports arbitrary bandwidths from 5 MHz to 72 MHz. When calibrated, the bandwidth is accurate to ±2,5%. A built-in filter bypass option enables wider bandwidths while maintaining programmed gain and common mode control settings. Programmable bias settings enable performance/power dissipation trade-off optimised for each application. Filter calibration is accomplished with any reference clock rate from 20 to 80 MHz. One time programmable memory allows the user to ‘set and forget’ parameters like gain and bandwidth.
