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. • 1.1 GHz Toggle Frequency • Supply Voltage of 4.5 to 5.5 V • Low–Power 7.5 mA Typical • Operating Temperature Range of –40 to +85°C • Short Setup Time (t set) 16ns Maximum @ 1.1 GHz • Modulus Control Input Level Is Compatible With Standard CMOS and TTL. Maximum Input Voltage Should Be Limited to 6.5 Vdc FUNCTIONAL TABLE SW MC Divide Ratio H H 64 H L 65 L H 128 L L 129 NOTES: 1. SW: H = VCC, L = Open. A logic L can also be applied by grouunding this pin, but this is not recommended due to increased power soncumption. 2. MC: H = 2.0 V to VCC, L = GND to 0.8 V. Figure 1.
