JTSxxCS-Serie is a (voltage controlled) temperature-compensated crystal oscillator with sophisticated features to meet the requirement for the reference clock of Stratum 3. Its comprehensive compensation technique can guarantee very tight stability over a wide range of operating temperatures. The short- and long-term aging is well controlled to only allow a total +/-4.6ppm frequency excursion with all defined environmental variations and up to 20-year duration. The clipped sinewave (VC)TCXOs supplied by 1.8V up to 3.3V in a 3225 package are compliant with ITU-T G.8262 Options 1 & 2 and Stratum 3 GR-1244 Core & CR-253-Core. It is dedicated well to synchronous Ethernet equipment clocks (EECs) and Optical-Transport-Network equipment clocks (OECs).
