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
μ
A typical when
the standby pin SB is switched LOW disabling the prescaler.
