CF5036 series
2.5V LVPECL Output Oscillator ICs
OVERVIEW
The CF5036 series are 2.5V operation, differential PECL output oscillator ICs. They support 50MHz to
250MHz 3rd overtone oscillation and 50MHz to 700MHz fundamental oscillation. The devices are fabricated
using a proprietary BiCMOS process, enabling a high-frequency oscillator circuit and differential LVPECL
output buffer to be incorporated on a single chip. The CF5036 series can be used to construct high-frequency
PECL output 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.

Oscillator block equivalent circuit
The CF5036 series oscillator circuit has a C0 cancel circuit built-in to improve the oscillator margin. If power is applied when there is an
open circuit between XIN and XOUT, self oscillation may occur, which is not abnormal. Users should confirm that the oscillator operates
normally when a crystal unit is connected.

FUNCTIONAL DESCRIPTION
Standby Function
When OE goes LOW, the oscillator stops and the output pins (OUT, OUTN) become high impedance.

O

High impedance
Power-saving Pull-up Resistor
The OE pin pull-up resistance changes in response to the input level (HIGH or LOW). When OE is tied LOW
(standby state), the pull-up resistance becomes large, reducing the current consumed by the resistance. When
OE is open circuit, the pull-up resistance becomes small, decreasing the susceptibility to the effects of external
noise.
