MC12093

÷2, ÷4, ÷8 1.1 GHz Low

Power Prescaler with

Stand−By Mode

Description

The MC12093 is a single modulus prescaler for low power

frequency division of a 1.1 GHz high frequency input signal.

MOSAIC V

™ technology is utilized to achieve low power dissipation

of 6.75 mW at a minimum supply voltage of 2.7 V.

On−chip output termination provides output current to drive a

2.0 pF (typical) high impedance load. If additional drive is required

for the prescaler output, an external resistor can be added parallel from

the OUT pin to GND to increase the output power. Care must be taken

not to exceed the maximum allowable current through the output.

Divide ratio control inputs SW1 and SW2 select the required divide

ratio of

÷2, ÷4, or ÷8.

Stand−By mode is featured to reduce current drain to 50

mA typical

when the standby pin SB is switched LOW disabling the prescaler.
