DESCRIPTION
The LTC®1064-1 is an 8th order, clock sweepable elliptic (Cauer) lowpass switched capacitor filter. The passband ripple is typically ±0.15dB, and the stopband attenuationat 1.5 times the cutoff frequency is 68dB or more. An external TTL or CMOS clock programs the value of the filter’s cutoff frequency. The clock to cutoff frequency ratio is 100:1.
