Zusammenfassung:With the selectable 50:1/100:1 clock-to-corner-ratio pin and two uncommitted op amps, the clock-oscillator IC provides both an anti-aliasing filter and a reconstruction filter. Furthermore, the clock output of the MSELP can drive another switched-capacitor high-pass filter. Armed with a clock-to-corner frequency ratio of 1000:1, the MSHN6 sixth-pole high-pass/notch filter puts a decade between the corners of the bandpass filters.
