The MC12028A can be used with CMOS synthesizers requiring positive
edges to trigger internal counters such as Motorola’s MC145XXX series in a
PLL to provide tuning signals up to 1.1 GHz in programmable frequency
steps.
The MC12028B can be used with CMOS synthesizers requiring negative
edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of a 32/33 or 64/65 divide
ratio as desired.
The Modulus Control (MC) selects the proper divide number after SW has
been biased to select the desired divide ratio.
NOTE: The “B” Version Is Not Recommended for New Designs

NOTES:
1.SW: H = VCC, L = Open. A logic L can also be applied by grouunding this pin,
but this is not recommended due to increased power soncumption.
2.MC: H = 2.0 V to VCC, L = GND to 0.8 V.
