MC12022A MC12022B
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.
