More precise timing devices are required for 5G, however, there are issues with high cost, size and power consumption, etc. in OCXO.
Therefore, Murata will continue to improve the accuracy of the TCXO in order to create an environment where the OCXO is no longer required.
Murata’s precision TCXO has temperature characteristics equivalent to an OCXO with an accuracy of +/-200 ppb over a temperature range of -40 ºC to 85 ºC. The product ensures the accuracy of the holdover and free-run required by G.8262 in the EEC (Ethernet Equipment Clock).
In order to withstand harsher environments, we are now developing products with a wider temperature range. In addition to small cells, the product is suitable for high-precision synchronous systems using IEEE1588/PTP or synchronous Ethernet.
