TheMSMXVHF Mixer with selectable high frequen- cy 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 capac- itors) are required, Two external clocks are need- ed for the mixer and filter functions. Lower cur- rent, 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 included in the 16 pin version.

The filter type is selected using the two filter se- lect pins, TYPE and FSEL, FSEL is a CMOS level pin that selects lowpass or bandpass response (lowpass = 0, bandpass = 2). TYPE Is a tertiary control pin that selects the filter response. State 0 is VSS, state 1 is AGND and state 2 is VDD. TYPE Lowpass Bandpass

The clock to corner select pin F0 is a CMOS level pin where HIGH is clock to corner of 12.5 to 1 (25 to 1 for Bessel) and LOW is clock to corner of 6.25 to 1 (12.5 to 1 for Bessel). The sample rate ratio is twice the clock to corner ratio (double sampling).
