2.0 GHz Super Low Power

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 Lansdale’ 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.

  • 2.0 GHz Toggle Frequency
  • The ML12054A is Pin and Functionally Compatible with the Motorola MC12031
  • Low Supply Current 2.0 mA T ypical
  • 2.6mA Maximum, 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 V oltage Should Be Limited to 6.5 Vdc
  • Operating Temperature Range TA = –40 to 85°C FUNCTIONAL TABLE SW MC Divide Ratio H H 64 H L 65 L H 128 L L 129 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.
