The DSC1001DI4-010.0503T is a 10.0503 MHz MEMS-based XO (standard) from Microchip's DSC1001 series, delivering a CMOS output in a 2.50mm x 2.00mm 4-SMD no-lead package.
The oscillator operates across a 1.8V to 3.3V supply range, so it can be driven from a 2.5V rail without an additional regulator — a common question for mixed-voltage designs.
Yes, it carries an AEC-Q100 rating, which means it has passed automotive-grade reliability stress tests including temperature cycling and ESD sensitivity.
Yes. The supply voltage range is 1.8V to 3.3V, so a 2.5V rail is within spec without any external regulation.
The base resonator is MEMS rather than quartz. MEMS oscillators typically offer better shock and vibration resistance, faster start-up, and smaller package sizes. The DSC1001 series uses a silicon MEMS die, which also contributes to the wide supply voltage tolerance and the standby power-down feature.
