The DSC1001DI1-033.3333T is a standard XO built around a MEMS resonator, outputting a CMOS-level 33.3333 MHz clock from a 1.8V to 3.3V supply rail.
That lets a system-level PMIC or GPIO gate the clock tree without an external load switch. During normal operation the device draws 7.2 mA max at 33.3333 MHz. For a multi-clock board running several MEMS oscillators, the total current budget stays under 30 mA — negligible against the processor core draw.
Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The MEMS die is hermetically sealed at the wafer level, so no moisture sensitivity level concerns beyond the standard JEDEC floor life.
No direct pin-compatible replacement is listed; the DSC1001DI1-033.3333T is the specific frequency and stability grade you need. If the frequency or supply voltage changes, the DSC1001 family includes other order codes with the same package and pinout.
