Table 1. Features & benefits of ThermSymEros series

Compared with the quartz-based Temperature Compensated Crystal Oscillator (TCXO) and Micro Electro Mechanical Systems (MEMS) TCXO, ThermSymEros series powerfully supports better timing solution performance such as frequency stability over temperature as shown in Fig. 2, phase noise as shown in Fig. 3, aging, holdover, etc. to supply good external reference clock connection to PLL chipset for timing synchronization standards related to SyncE, IEEE 1588 and SONET/SDH applying in 5G network infrastructure.
