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.
