MC12034B

Order this document by MC12034A/D 2.0GHz Dual Modulus Prescaler MC12034A MC12034B The MC12034A 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. The MC12034B can be used with CMOS synthesizers requiring negative edges to trigger internal counters such as Fujitsu’s MB87001. 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. 2.0 GHz Toggle Frequency Supply Voltage 4.5 to 5.5 V MC12034A for Positive Edge Triggered Synthesizers 12mA Maximum, –40 to 85°C, VCC = 5.5 Vdc Modulus Control Input is Compatible with Standard CMOS and TTL Low–Power 8.5 mA Typical FUNCTIONAL TABLE SW MC Divide Ratio HH 32 HL 33 LH 64 LL 65 NOTES: 1.
