Selectable Very High Frequency LP/BP Filter
Data Sheet
Description
Features
·
TheMSVHFS1-6 is a selectable very high frequen-
cy lowpass/bandpass filter CMOS IC. The low-
pass response can be a 6 pole Butterworth,
Elliptic or Bessel filter. The band pass response
can be a six pole full, third or sixth octave
bandpass filter. The device uses switched-capacitor
filters (SCF) and no external components (except
for decoupling capacitors) are required, Two exter-
nal clocks are needed for the mixer and filter
functions. Lower current, and lower frequencies
are pin selected.
