The E2OCXO from Rakon is an Oven Controlled Crystal Oscillator (OCXO) that enhances existing synchronization capabilities on a network synchronizer evaluation board by adding frequency error exchange processing and aging compensation to the system. It uses an Error Exchange Synchronisation technique designed to significantly enhance the capability of OCXO holdover by using a network processor and a synchronization PLL available in IEEE 1588 implementations. The PLL and the processor calculate the error between the OCXO frequency and the 1 PPS signal and feed it back to the OCXO for aging compensation. It combines the frequency residual error due to temperature variations and aging compensated error and feeds it back into the processor for system frequency correction.
The E2OCXO is ideal for O-RAN equipment vendors who require turnkey, cost-effective and miniaturized solutions. It is available in packages that measure 14 x 9 mm, 9 x 7 mm, or 7 x 5 mm and is ideal for 5G DUs, RAN, radios and telecom data center applications.
