MC12095

2.5 GHz Low Power

Prescaler With Stand−By

Mode

Description

The MC12095 is a single modulus prescaler for low power

frequency division of a 2.5 GHz high frequency input signal.

MOSAIC V

™ technology is utilized to achieve low power dissipation

of 24 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 in 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 input (SW) selects the required divide ratio of

÷2 or ÷4. Stand−By mode is available to reduce current drain to

100

mA typical when the standby pin SB is switched LOW disabling

the prescaler.
