Order this document by MC12054A/D 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 • • • • • • MECL PLL COMPONENTS ÷64/65, ÷128/129 LOW POWER DUAL MODULUS PRESCALER SEMICONDUCTOR TECHNICAL DATA 8 1 The MC12054 is Pin and Functionally Compatible with the MC12031 Low Power 2.0 mA Typical D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) 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 8 1 MOSAIC V is a trademark of Motorola SD SUFFIX PLASTIC PACKAGE CASE 940 (SSOP–8) FUNCTIONAL TABLE SW MC Divide Ratio H H 64 H L 65 L H 128 L L 129 PIN CONNECTIONS NOTES: 1.
