125 MHz MEMS clock source for automotive and industrial boards
The DSC1121BI2-125.0000 is a 125 MHz MEMS-based oscillator (XO) with CMOS output, rated across -40°C to 85°C and qualified to AEC-Q100 — a fit for engine-bay ECUs, ADAS sensor modules, and outdoor telecom gear where a quartz crystal would drift or fail under vibration. Frequency stability is held to ±25 ppm over the full temperature and voltage range, which keeps the clock edge jitter within the timing budget for 125 MHz serial links like Gigabit Ethernet or LVDS interfaces.
Supply voltage flexibility and enable/disable control
The 2.25V to 3.6V supply range lets the oscillator run directly off a 2.5V or 3.3V rail without an intermediate LDO — one less component on the BOM. An enable/disable pin lets the system gate the clock output; when disabled the supply current drops to 22 mA max, useful for power-cycled sensor nodes or multi-clock-domain power management.
The part is available for new designs and production builds.
