The 5036 series are 2.5V operation, differential LV-PECL output oscillator ICs. They support 50MHz to
400MHz 3rd overtone oscillation and 50MHz to 600MHz fundamental oscillation. The devices are fabricated
using a proprietary BiCMOS process, enabling a high-frequency oscillator circuit and differential LV-PECL
output buffer to be incorporated on a single chip. The 5036 series can be used to construct high-frequency LV-
PECL output oscillators.

The 5036G×/A×/B×/C×/D×(T)/E× 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.
The XOUT pin of 5036E× version emphasizes high frequency characteristics. Accordingly, its electrostatic withstand voltage is significantly
lower than that of the other pins. ESD breakdown prevention handling precautions are strongly recommended.
