Operates from a 1.8V to 3.3V supply rail — wide enough to share a common 3.3V or 1.8V bus without an extra regulator.
Package and footprint for reflow
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Standard surface-mount footprint — no via-in-pad or exotic stencil required. Check the MSL before the oven; MEMS oscillators typically have MSL 1 or 2, but confirm with the lot date code to avoid popcorning.
No direct pin-compatible second source from another manufacturer; the DSC1004 series itself covers multiple frequencies and stabilities if a variant is needed.
