MEMS oscillator for automotive clocking
Its 1.71V–3.63V supply range covers 1.8V, 2.5V, and 3.3V rails without a separate regulator — a single BOM line serves multiple voltage domains in an ECU.
This is a current-design-in part, not a last-time-buy candidate. No official second-source or pin-compatible cross-reference is documented, but the DSC60XX family shares the same 4-VFLGA footprint, so a different frequency variant could be swapped if the clock tree allows.
Package and integration fit
Housed in a 4-VFLGA package measuring 1.6mm x 1.2mm with a seated height of 0.89mm. The 4-pin land-grid array has no exposed leads — the solder joints are under the package, so X-ray inspection is the standard post-reflow check. For a battery-backed RTC or always-on sensor node, that difference extends standby time measurably.
