CF5019 series High-Frequency, 3rd Overtone Crystal Oscillator Module ICs www.datasheet4u.com OVERVIEW The CF5019 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-p
