The MF10-N consists of 2 independent and extremely easy to use, general purpose CMOS
active filter building blocks. Each block, together with an external clock and 3 to 4 resistors,
can produce various 2nd order functions. Each building block has 3 output pins. One of the outputs
can be configured to perform either an allpass, highpass or a notch function; the remaining 2
output pins perform lowpass and bandpass functions. The center frequency of the lowpass and
bandpass 2nd order functions can be either directly dependent on the clock frequency, or they can
depend on both clock frequency and external resistor ratios. The center frequency of the notch and
allpass functions is directly dependent on the clock frequency, while the highpass center frequency
depends on both resistor ratio and clock. Up to 4th order functions can be performed by cascading
the two 2nd order building blocks of the MF10-N; higher than 4th order functions can be obtained by
cascading MF10-N packages. Any of the classical filter configurations (such as Butterworth, Bessel,
Cauer and Chebyshev) can be formed.
