ML12054A
2.0 GHz Super Low Power
Dual Modulus Prescaler
Legacy Device: Motorola MC12054A
The ML12054A is a super low power dual modulus
prescaler used in phase-locked loop applications with low
power dissipation of 5.4 mW at a minimum supply voltage
of 2.7 V.
The ML12054A can be used with CMOS synthesizers
requiring positive edges to trigger internal counters such as
Motorola's MC145xxx or Lansdaleโ€™s ML145xxx series in a
PLL to provide tuning signals up to 2.0 GHz in programma-
ble 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 num-
ber after SW has been biased to select the desired divide
ratio.
โ€ข 2.0 GHz Toggle Frequency
โ€ข The ML12054A is Pin and Functionally Compatible
with the Motorola MC12031
โ€ข Low Supply Current 2.0 mA Typical
โ€ข 2.6mA Maximum, VCC = 2.7 to 5.5 Vdc
โ€ข Short Setup Time (Tset) 10ns Maximum @ 2.0 GHz
โ€ข Modulus Control Input Level is Compatible with
Standard CMOS and TTL
โ€ข Maximum Input Voltage Should Be Limited to 6.5 Vdc
โ€ข Operating Temperature Range TA = โ€“40 to 85ยฐC

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.
