MEMS oscillator with AEC-Q100 for automotive clocking
The DSC1001AI1-050.0000 is a 50 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a CMOS output with a standby (power-down) function that drops supply current to 15 µA max when disabled.
Supply flexibility and power-down for rail design
The 1.8V to 3.3V supply range means the same oscillator can run off a 1.8V core rail, a 2.5V I/O rail, or a 3.3V system rail without a separate regulator — one BOM line covers multiple voltage domains.
Package and footprint for rework and layout
Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad aids thermal transfer to the PCB ground plane, which matters when the oscillator sits near a hot processor or regulator.
