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.
