The DSC1001DI2-028.3220T is a 28.322 MHz MEMS-based XO (Standard) that outputs CMOS levels from a 1.8 V to 3.3 V supply rail — the wide voltage range lets it sit on a shared 3.3 V bus or a lower 1.8 V core rail without a separate LDO. That puts it in the cabin or chassis domain, not the engine bay; for under-hood 125 °C you would step to the DSC1001's high-temp variant. The 4-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — this is a compact footprint for space-constrained automotive PCBs like ADAS camera modules or keyless-entry receivers.

Frequently asked questions
Does the DSC1001DI2-028.3220T have a standby mode?
Yes, the standby (power-down) function reduces supply current to 15 µA max when the output is disabled, preserving battery life in sleep-capable automotive modules.
