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.
