Order this document by MC12053A/D $ ! " " ! !! # The MC12053A is a super low power ÷64/65, ÷128/129 dual modulus prescaler. 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 • • • • • • MECL PLL COMPONENTS ÷64/65, ÷128/129 LOW POWER DUAL MODULUS PRESCALER WITH STAND–BY MODE SEMICONDUCTOR TECHNICAL DATA 8 1 Supply Voltage of 2.7 to 5.5 V D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) 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 8 1 MOSAIC V is a trademark of Motorola SD SUFFIX PLASTIC PACKAGE CASE 940 (SSOP–8) FUNCTIONAL TABLE SW MC Divide Ratio H H 64 H L 65 L H 128 L L 129 PIN CONNECTIONS NOTES: 1.
