MEMS oscillator at 50 MHz – what it buys the timing rail
The DSC1001AE1-050.0000T is a MEMS-based XO (Standard) oscillator delivering a fixed 50 MHz CMOS output — the MEMS resonator eliminates the quartz cold-start and vibration sensitivity that can cause frequency drift in crystal-based designs. It accepts any supply between 1.8 V and 3.3 V without a separate regulator, which simplifies rail assignment on mixed-voltage boards.
Automotive-grade qualification and temperature envelope
The operating range is -20°C to 70°C, which covers most passenger-cabin and infotainment environments but does not extend to the -40°C cold-crank or 105°C under-hood extremes — confirm the application ambient before committing.
