Consider MC12052A for New Designs
MC12022B
1.1GHz Dual Modulus Prescaler
The MC12022A 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 1.1GHz in programmable frequency
steps.
The MC12022B can be used with CMOS synthesizers requiring negative
edges to trigger internal counters.
A Divide Ratio Control (SW) permits selection of a 64/65 or 128/129 divide
ratio as desired.
The Modulus Control (MC) selects the proper divide number after SW has
been biased to select the desired divide ratio.

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.
