MC12054A

Order this document by MC12054A/D 2.0 GHz Super Low Power Dual Modulus Prescaler 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 The MC12054 is Pin and Functionally Compatible with the MC12031 Low Power 2.0 mA Typical 2.6mA Maximum, –40 to 85°C, VCC = 2.7 to 5.5 Vdc Short Setup Time (tset) 10ns Maximum @ 2.0 GHz Modul...
