CF5019 series
High-Frequency, 3rd Overtone Crystal Oscillator Module ICs
OVERVIEW
The CF5019 series are high-frequency, 3rd overtone crystal oscillator module ICs. They incorporate an oscilla-
tor 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 technol-
ogy, which suppresses oscillator characteristic variations due to changes in temperature and voltage to a mini-
mum. The CF5019 series can be utilized to construct stable, high-frequency, 3rd overtone crystal oscillators.
FEATURES

tor circuit

I – 40 to 85°C operating temperature range
I Oscillator capacitors with excellent frequency
response built-in
I Feedback resistors with good temperature charac-
teristics built-in
I Standby function
• High impedance in standby mode, oscillator stops
I Low standby current
• Power-saving pull-up resistor built-in
I Oscillation detector function
I CMOS output duty level (1/2VDD)
I 50 ± 5% output duty (at 1/2VDD)
I 30pF output load (3.3V operation)
I Molybdenum-gate CMOS process
I Chip form (CF5019AL×)
APPLICATIONS
I Crystal oscillator modules (3rd overtone oscillation)

*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.
