The DSC1001CI1-133.3333T is a standard XO (Standard) clock generator built around a MEMS resonator rather than a quartz crystal, delivering a 133.3333 MHz CMOS output in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm. The AEC-Q100 rating confirms the device passed automotive-grade reliability stress, making it a candidate for under-hood or cabin-domain clock trees where the ECU requires a known qualification pedigree.
Supply range and standby power-down
Maximum supply current is 8.7 mA — low enough that the thermal budget inside a sealed ECU module is not a concern at this frequency.
