TXC announces a new series of miniaturized Oven-Controlled Crystal Oscillator (OCXO). (OG product series) TXC Corporation

OG Product Outline


TXC newly developed world's smallest SMD-type miniaturized OCXO in 9.7mm x 7.5mm x 5.5mm package size. It combines a miniature oven structure design with high stability SC-cut SMD X’tal, and integrated circuit technology to achieve excellent temperature stability, low phase noise, high frequency stability against airflow environment and superior reliability compared to traditional discrete OCXO. The miniaturized package size could reduce the power consumption and also save the layout space.
TXC’s OG-series could be the best reference clock choice for telecommunication infrastructure, Base station, Small cell, OTN, PTN, Switch, Router, precise timing network such as IEEE1588, SyncE, and Smart Grid, testing equipment…etc.
