MC12022B

www.DataSheet4U.com MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1.1GHz Dual Modulus Prescaler MC12022A MC12022B The MC12022A 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 1.1GHz in programmable frequency steps. The MC12022B can be used with CMOS synthesizers requiring negative edges to trigger internal counters. 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. MECL PLL COMPONENTS ÷64/65, ÷128/129 DUAL MODULUS PRESCALER 1.1 GHz Toggle Frequency Supply Voltage of 4.5 to 5.5V Low–Power 7.5mA Typical Operating Temperature Range of –40 to +85°C Short Setup Time (tset) 16ns Maximum @ 1.1GHz Modulus Control Input Level Is Compatible With Standard CMOS and TTL.
