The MSMXVHF Mixer with selectable high frequency lowpass/bandpass filter IC is a CMOS chip that has an independent mixer for IF functions. The output of the mixer can be tied to either a lowpass or a band-pass filter. The lowpass response can be a 6 pole Butterworth, Elliptic or Bessel filter. The band pass response can be a six pole full, 1/3 or 1/6 octave bandpass filter. The device uses switched-capacitor filters and no external components (except for decoupling capacitors) are required, Two external clocks are needed for the mixer and filter functions. Lower current, and lower frequencies are pin selected.

An external selectable gain setting pin, along with a power down and clock to corner ratio select pin are also included.
