NPC CF5014AL4

CF5014 series
Crystal Oscillator Module ICs
OVERVIEW
The CF5014 series are fundamental frequency crystal oscillator ICs. They are available for frequencies up to
60MHz. The chip layout is optimized, resulting in a large reduction in chip size, when compared to existing
devices.

1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the
oscillator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.

FUNCTIONAL DESCRIPTION
Standby Function
When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.
INHN
Q
Oscillator
HIGH (or open)
Any fO, fO/2, fO/4, fO/8 or fO/16 output frequency
Normal operation
LOW
High impedance
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.
