The DSC1001DI1-020.0000 is a 20 MHz MEMS-based XO (Standard) with CMOS output, built for applications where a quartz crystal's shock and vibration limits are a known failure mode — the MEMS resonator handles 50,000 g shock and 70 g vibration without frequency shift, which is why it carries AEC-Q100 qualification. Supply voltage spans 1.8V to 3.3V, covering 1.8V, 2.5V, and 3.3V logic rails without a separate LDO — the same BOM position works across a multi-rail board by tying the supply pin to the appropriate rail.
Active supply current is 6.3 mA max at 20 MHz, so the standby savings are a factor of 420× — meaningful for a CAN transceiver or sensor node that spends 99% of its life asleep.
Housed in a 4-SMD, no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — the 0.098" × 0.079" footprint fits under a shielding can or on a dense mixed-signal board where every mm² counts.
