CF5014 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
Any fO, fO/2, fO/4, fO/8 or fO/16 output frequency
High impedance
Oscillator
Normal operation
Stopped
Power-save Pull-up Resistance
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.
