MOTOROLA MC12054

Order this document by MC12054A/D
The MC12054A is a super low power dual modulus prescaler used in
phase-locked loop applications. Motorola’s advanced Bipolar MOSAIC V
technology is utilized to achieve low power dissipation of 5.4 mW at a
minimum supply voltage of 2.7 V.
The MC12054A 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 2.0 GHz in programmable frequency
steps.
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.
