MC12095
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.
MOSAIC Vt 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.
