Motorola’s advanced Bipolar MOSAIC ™ V technology is utilized to achieve low power dissipation of 4.3 mW at a minimum supply voltage of 2.7 V. The Divide Ratio Control input, SW, permits selection of divide ratio as desired. A HIGH on SW selects ÷64/65; an OPEN on SW selects ÷128/129. The Modulus Control input, MC, selects the proper divide number after SW has been biased to select the desired divide ratio. Stand–by mode is featured to reduce current drain to 50 µA typical at 2.7 V when the stand–by pin, SB, is switched LOW, disabling the prescaler. On–chip output termination provides 500 µA (typical) output current, which is sufficient to drive a CMOS synthesizer input high impedance load (8.0 pF typical). • 1.1 GHz Toggle Frequency • Supply Voltage of 2.7 to 5.5 V • Low Power 1.5 mA Typical at VCC = 2.7 V • Operating Temperature Range of –40 to 85°C • On–Chip Output Termination • The MC12053A Is Pin and Functionally Compatible With the MC12036 • Modulus Control Input Level Is Compatible With Standard CMOS and TTL 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 – 0.5 to 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 & SB: H = 2.0 V to VCC, L = Gnd to 0.8 V.
