SEMICONDUCTOR TECHNICAL DATA
1.1GHz Low Power Dual
Modulus Prescaler
With On-Chip Output Termination
The MC12022TSA 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. This device is a reduced current drain version of the
MC12022A/B with the addition of on–chip output termination.
The MC12022TSB 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
