2.0 GHz Super Low Power
Dual Modulus Prescaler
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.
• 2.0 GHz Toggle Frequency
• The MC12054 is Pin and Functionally Compatible with the MC12031
• Low Power 2.0 mA Typical
• 2.6mA Maximum, –40 to 85°C, VCC = 2.7 to 5.5 Vdc
• Short Setup Time (tset) 10ns Maximum @ 2.0 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.
