AEC-Q100 qualification means this oscillator has passed automotive-grade reliability stress tests — suitable for infotainment, ADAS camera modules, or body-control ECUs where a quartz failure at temperature extremes is not acceptable. The enable/disable function lets the system pull the output to high-impedance when the clock tree is idle, cutting supply current from 35 mA max to 22 mA max — a useful power-save for battery-backed or thermal-constrained designs. ## Supply voltage and package fit Wide supply range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external LDO — the oscillator operates directly from the core or I/O supply.","metaTitle":"DSC1121AE2-050.0000 MEMS XO 50 MHz CMOS AEC-Q100 Active","metaDescription":"Microchip DSC1121AE2-050.0000 MEMS XO, 50 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified, active production.

This allows the clock tree to be disabled without removing power from the oscillator."},{"question":"Does DSC1121AE2-050.0000 have a tri-state output?","answer":"Yes — the enable/disable function puts the output into high-impedance when disabled.
