DESCRIPTIO
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 attenuation at 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.
