The DSC1001DI5-031.2500 is a MEMS-based XO (Standard) oscillator delivering a fixed 31.25 MHz CMOS output — a common frequency for Ethernet PHYs, USB controllers, and general-purpose processor clocks. It operates from a 1.8V to 3.3V supply rail, covering the three most common digital logic voltages without needing an external regulator.
The 4-SMD no-lead package (2.50mm x 2.00mm footprint, 0.90mm seated height) suits space-constrained PCBs in engine control units, ADAS modules, and infotainment boards.
Power budget and standby behaviour
Max supply current is 7.2 mA during active oscillation — low enough for a 3.3V rail shared with other logic without thermal worry.
