CF5019

High-Frequency, 3rd Overtone Crystal Oscillator Module ICs

Nippon Precision Circuits  

CF5019 series

FUNCTIONAL DESCRIPTION

Standby Function

When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.

INHN

HIGH (or open)

LOW

Q

fO output frequency

High impedance

Oscillator

Normal operation

Stopped

Power-saving Pull-up Resistor

The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW

(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
