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.

FUNCTIONAL DESCRIPTION
Standby Function
When INHN goes LOW, the device is in standby mode. The Q output becomes high impedance and the oscilla-
tor circuit stops.
INHN

LOW
Q

Normal operation

f

O
High impedance
Power-saving Pull-up Resistor
The INHN pin pull-up resistance changes in response to the input level (HIGH or LOW). When INHN is tied
LOW, the pull-up resistance becomes large, reducing the current consumed by the resistance. When INHN is
left open, the pull-up resistance becomes small, such that even if the input is affected by external noise the out-
puts are stable due to INHN being tied HIGH by the pull-up resistor.
Oscillation Detector Function
The devices also feature an oscillation detector circuit. This circuit functions to disable the outputs until the
oscillator circuit starts. This prevents abnormal oscillator output at oscillator start-up when power is applied or
when INHN is switched.
