Three TCXOs and VC-TCXOs use DoubleSeal technology for stability

Three TCXOs and VC-TCXOs from Epson Europe Electronics, the TG-5500CA and TG-5501CA TCXOs and VC-TCXOs, have a frequency range of 10 to 50MHz.

Epson’s patented DoubleSeal technology is used in the TG-550x TCXOs and VC-TCXOs which are designed for network synchronisation, small cell and microwave radio applications where stability over varying environmental conditions is essential.

With ±250 parts per billion temperature stability over -40 to +85 degrees C, 6×10-11 at 1s root Allan variance and less than ±10 parts per billion 24-hour holdover, the TG-550x TCXOs and VC-TCXOs deliver the stability needed to meet the latest networking standards. Target applications are wireless projects, such as S3 and 3GPP LTE home-area femtocell radios. They can also be used in SONET BITS/SETS and packet timing (network synchronisation), to G.8262 EEC-1 & EEC-2 and emerging G.826x & G.827x ITU-T specifications

The TCXOs use a combination of crystal and package technologies in a 7.0 x 5.0mm ceramic cavity to provide environmental isolation and low airflow sensitivity. These characteristics make them particularly suitable for synchronisation applications.

Epson specialises in efficient, compact and precision technologies, from inkjet printers and digital printing systems to 3LCD projectors, watches and industrial robots. The company serves the inkjet, visual communications, wearables and robotics markets.

Led by the Japan-based Seiko Epson Corporation, the Epson Group comprises more than 76,000 employees in 87 companies around the world.
