Increased Design Margin for Network Timing Cards Stratum 3 TCXO with lower phase noise and 0.34 ppmp-p stability including hysteresis M615x Series 12.8 MHz Typical Phase Noise Download more M615x Series Stratum 3 TCXO/VCTCXO We’re all online now. And it may not be obvious but time matters as we send all those bits back and forth. Whether buying on EBay, trading stock, emailing, streaming video, or online gaming… exact relative time and time of day are critical. The telecom industry solved this in the late 80’s with the synchronous optical network (SONET) and it’s timing hierarchy: Stratum 1, …. down to Stratum 15, where Stratum 0 is an atomic clock. M615x Series provides network and wireless engineers extremely tight stability over temperature and time. Proprietary in-house crystal processing enables full Stratum 3 compliance. But check your requirements carefully: M615x Series stability specifications include hysteresis where competing solutions may not. For Internet business servers, it’s Stratum 3 that applies. Stratum 3 clocks in a lab environment must drift less than 0.04 ppm per day after loss of sync to a Stratum 2 reference. In real-world operation over all possible conditions including temperature, holdover stability must be less than 0.34 ppmp-p per day MtronPTI’s M610x Series TCXO already meets stability and holdover for Stratum 3 applications. Select the compatible M615x Series instead and you’ll get 5 dB to 6 dB lower close-in phase noise – more design margin for the rest of your board or potentially lower overall system bit error rate. The same stringent processes that boost long-term stability and minimize frequency shift after reflow also bring excellent g-sensitivity (1.5 ppb/g) and lower close-in phase noise (typically -102 dBc/Hz @ 10 Hz offset compared to about -95 dBc/Hz on the M610x). Lower phase noise, low g-sensitivity, low drift, 8 MHz to 38.88 MHz: the M615x Series is ideal for any application requiring a stable, quiet timing reference source.
