CF5035

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 feedwww.DataSheet4U.com back resistor built-in. The oscillation characteristics feature little variation with supply voltage, providing stable 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-frequency crystal oscillators.
