1.1 GHz 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.
