MOTOROLA RF/IF DEVICE DATA

2.5 GHz Low Power Prescaler

With Stand-By Mode

The MC12095 is a single modulus prescaler for low power frequency

division of a 2.5 GHz high frequency input signal. Motorola’s advanced

MOSAIC

™ V technology is utilized to acheive 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

µA typical when

the standby pin SB is switched LOW disabling the prescaler.

NOTE: For applications up to 1.1 GHz, please consult the MC12093

datasheet.
