Suntsu Introduces High Temperature Miniature Size SMD OCXO

Suntsu Electronics new miniature size SMD OCXO operates at higher temperatures than an average OCXO. Due to high-density mounting, the internal temperature of base stations is raised to 95°C. For this reason, high temperature-compatible clocks with high frequency stability and low phase noise performances are required.

SuntsuThis new miniature OCXO provides high frequency stability between -40°C to 95°C and low phase noise. It comes in two SMD package sizes SOC09C (9.7mm x 7.4mm) and SOC14C (14.4mm x 9.4mm) that is sure to fit your design. This miniature OCXO ages at a rate of ±0.8ppb per day so long as other parameters are kept constant and features a holdover period of 1.5 hours. A frequency stability of ±20ppb is also available for special specifications of any design.

The telecommunications industry demands a lot from the transfer of large-capacity content such as video shares at high-speed transfer rates. Consequently, that also means there is demand for the installation of numerous small base stations. OCXOs are built to meet temperature requirements demanded by heater power. Normal operating temperatures for OCXOs fall between 75°C to 80°C for most commercial and industrial applications. With the rise of 5G infrastructures, there is an increased necessity of greater operating temperatures in OCXOs.

Suntsu’s Director of Engineering, KH Mun, added, “aside from telecommunications, our SMD OCXO can operate in military communications equipment, testing equipment, synthesizers, and digital switching”.
