1.1GHz Dual Modulus Prescaler;

MECL PLL COMPONENTS ÷64/65, ÷128/129 DUAL MODULUS PRESCALERThe 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.\nThe MC12022B can be used with CMOS synthesizers requiring negative edges to trigger internal counters.\nA 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.? 1.1 GHz Toggle Frequency\n? Supply Voltage of 4.5 to 5.5 V\n? Low–Power 7.5 mA Typical\n? Operating Temperature Range of –40 to +85°C\n? Short Setup Time (tset) 16ns Maximum @ 1.1 GHz\n? Modulus Control Input Level Is Compatible With Standard CMOS and TTL. Maximum Input Voltage Should Be Limited to 6.5 Vdc
