SEMICONDUCTOR TECHNICAL DATA
Legacy Device:
Motorola MC12052A
The ML12052 is a super low power dual modulus prescaler
used in phase–locked loop applications with low power dissipa-
tion of 2.7 mW at a minimum supply voltage of 2.7 V.
The ML12052 can be used with CMOS synthesizers requiring
positive edges to trigger internal counters such as Motorola's
MC145xxx or Lansdale’s ML145xxx 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 ML12052 is Pin and Functionally Compatible with the
Motorola or ON Semiconductor MC12022
• Low Power 1.0 mA Typical
• 2.0 mA Maximum, 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
• Operating Temperature Range TA = –40 to 85°C

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.
