5036 series
SEIKO NPC CORPORATION —1
2.5V LV-PECL Output Oscillator ICs
OVERVIEW
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.

*1. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscilla-
tor 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.
