What this MEMS oscillator does on your board
The DSC1201DI3-32M00000 is a MEMS-based XO (Standard) that generates a 32 MHz clock with CMOS output — no external crystal or load capacitors needed. It replaces a quartz crystal + oscillator circuit in one 6-VDFN package. AEC-Q100 qualification means this oscillator passed automotive-grade reliability stress tests — suitable for under-hood and cabin-domain applications where vibration and thermal cycling are routine.
Power budget: 27 mA active, 5 µA standby
Active supply current is 27 mA typ at 32 MHz — typical for a CMOS-output MEMS oscillator at this frequency. The standby (power-down) function drops consumption to 5 µA max, letting the system gate the clock tree on a sleep signal without a separate load switch. For a battery-powered ECU that spends most of its time asleep, the 5 µA standby current is below the self-discharge rate of a coin cell — the oscillator does not dominate the sleep budget.
Package and supply voltage flexibility
The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained PCBs. Surface-mount assembly; the 0.50 mm pitch pads fan out easily on a two-layer board. Supply voltage range is 2.5 V to 3.3 V, so the same part works across 3.3 V and 2.5 V logic domains without a separate level translator on the clock line.
