1.1 GHz Super Low Power

Dual Modulus Prescaler

With Stand-By Mode

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

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).

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.
