1.1 GHz Low-Voltage
Dual Modulus Prescaler
The MC12022LVA 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 MC12022LVB 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.
NOTE: The ªBº 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.
