1.1 GHz Super Low Power
Dual Modulus Prescaler
The MC12052A 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 2.7 mW at a
minimum supply voltage of 2.7 V.
The MC12052A 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.
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.
1.1 GHz Toggle Frequency
The MC12052 is Pin and Functionally Compatible with the MC12022
Low Power 1.0 mA Typical
2.0 mA Maximum, –40 to 85°C, VCC = 2.7 to 5.5 Vdc
Short Setup Time (tset) 16 ns Maximum @ 1.1 GHz
Modulus Control Input Level is Compatible with Standard CMOS and
TTL
Maximum Input Voltage Should Be Limited to 6.5 Vdc

NOTES: 1. SW: H = VCC, L = Open. A logic L can also be applied by grounding this pin,
but this is not recommended due to increased power consumption.
2. MC: H = 2.0 V to VCC, L = GND to 0.8 V.
