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.

MECL PLL COMPONENTS

÷64/65, ÷128/129

DUAL MODULUS PRESCALER

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 = V , 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 V , L = GND to 0.8 V.
