NPC CF5020ALC High-frequency, 3rd overtone crystal oscillator module ic Datasheet

CF5020 series
High-Frequency, 3rd Overtone Crystal Oscillator Module ICs
OVERVIEW
The CF5020 series are high-frequency, 3rd overtone crystal oscillator module ICs. They incorporate an oscillator circuit and an output buffer that operate at high frequency on a single chip. The oscillator circuit employs
CMOS inverters and a built-in damping resistor RD, reducing the crystal current compared with existing
devices. The damping resistor RD is fabricated using NPC’s unique high-precision thin-film resistor technology, which suppresses oscillator characteristic variations due to changes in temperature and voltage to a minimum. The CF5020 series can be utilized to construct stable, high-frequency, 3rd overtone crystal oscillators.

*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.
