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 “B” Version Is Not Recommended for New Designs

and TTL

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.
