Order this document by MC12033A/D 2.0 GHz Low Voltage Dual Modulus Prescaler MC12033A MC12033B The MC12033 is a high frequency low voltage dual modulus prescaler used in phase–locked loop (PLL) applications. A high frequency input signal up to 2.0 GHz is provided for cordless and cellular communication services such as DECT, PHS, and PCS. The MC12033 can be operated down to a minimum supply voltage of 2.7 V required for battery operated portable systems. The MC12033A can be used with CMOS synthesizer requiring positive edges to trigger internal counters such as Motorola’s MC145XXX series in a PLL to provide tuning signal up to 2.0 GHz in programmable frequency steps. The MC12033B can be used with CMOS synthesizers requiring negative edges to trigger internal counters. A Divide Ratio Control (SW) permits selection of a 32/33 or 64/65 divide ratio as desired. The Modulus Control (MC) selects the proper divide number after SW has been biased to select the desired divide ratio. NOTE...
