SEMICONDUCTOR TECHNICAL DATA
1.1GHz Prescaler With
Stand-By Mode
The MC12083 is a ÷2 prescaler for low power frequency division of a
1.1GHz high frequency input signal. On–chip output termination provides
output current to drive a 2pF (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.
Stand–By mode is featured to reduce current drain to 250µA typical
when the stand–by pin SB is switched LOW disabling the prescaler.
