NPC CF5017ALD-2 3rd overtone crystal oscillator module ic Datasheet

CF5017 series
3rd Overtone Crystal Oscillator Module ICs
OVERVIEW
The CF5017 series are 3rd overtone crystal oscillator ICs. Devices are available that provide 3rd overtone
oscillation in the range 30MHz to 80MHz. The oscillator circuit is comprised of feedback resistors with good
temperature characteristics and oscillation capacitors with excellent frequency response for stable 3rd overtone
oscillation. Also, the chip layout is optimized, resulting in a large reduction in chip surface area 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.

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.
