(electronics)
Alternating-current generator that supplies pumping energy for maser and parametric amplifiers; operates at twice or some higher multiple of the signal frequency.

In order to be capable of matching receivers and retaining receiver performance over some temperature range, the local oscillator power must be relatively constant even when the fundamental frequency pump oscillator power level changes.
The frequency multiplier remains well matched over this range and hence will not "pull" the pump oscillator frequency.
A charge pump oscillator pin replaces the LM2637's over-voltage protection pin, while maximum PWM duty cycle is increased from 95% to 100% to reduce loading to the charge pump during standby mode.
