CF5035 series
1.8V, High-frequency Crystal Oscillator Module ICs
OVERVIEW
The CF5035 series are 1.8V operation, high-frequency crystal oscillator module ICs. They support 70MHz to
165MHz (1.8V) and 70MHz to 220MHz (2.5 to 3.3V) 3rd overtone oscillation and fundamental oscillation
modes. The crystal oscillator circuit is a Colpitts oscillator with the necessary oscillator capacitors and feed-
back resistor built-in. The oscillation characteristics feature little variation with supply voltage, providing sta-
ble oscillation over a wide supply voltage range. The output circuit comprises a CMOS buffer that can operate
at high frequencies and drive a 15pF capacitance load. The devices are fabricated using a proprietary BiCMOS
process with the oscillator circuit and output buffer on a single chip, making them ideal as SMD-type high-fre-
quency crystal oscillators.

1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentica-
tion. 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.

1. Oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output is not resumed until after the
oscillator start-up time has elapsed.
