ML12054A

ML12054A 2.0 GHz Super Low Power Dual Modulus Prescaler MECL PLL COMPONENTS ÷64/65, ÷128/129 SEMICONDUCTOR TECHNICAL DATA 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 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 ML12054A is Pin and Functionally Compatible with the Motorola MC12031 • Low Supply Current 2.0 mA Typical • 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 Voltage Should Be Limited to 6.5 Vdc • Operating Temperature Range TA = –40 to 85°C FUNCTIONAL TABLE SW H H L L MC H L H L Divide Ratio 64 65 128 129 8 1 SO 8 = -5P PLASTIC PACKAGE CASE 751 (SO–8) CROSS REFERENCE/ORDERING INFORMATION MOTOROLA LANSDALE PACKAGE SO 8 MC12054AD ML12054A-5P Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.
