Motorola’s advanced Bipolar MOSAIC ™ V technology is utilized to achieve low power dissipation of 2.7 mW at a minimum supply voltage of 2.7 V. The MC12052A 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 1.1 GHz in programmable frequency steps. 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 • The MC12052 is Pin and Functionally Compatible with the MC12022 • Low Power 1.0 mA Typical • 2.0 mA Maximum, –40 to 85°C, VCC = 2.7 to 5.5 Vdc • Short Setup Time (tset) 16 ns 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 MOSAIC V is a trademark of Motorola 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 grounding this pin, but this is not recommended due to increased power consumption. 2. MC: H = 2.0 V to VCC, L = GND to 0.8 V.
