The supply voltage range spans 1.8 V to 3.3 V, so the same oscillator serves 1.8 V logic, 2.5 V I/O, and 3.3 V peripheral rails without a separate LDO or level translator.
Frequency stability and package footprint
The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm, so it fits into compact IoT modules and automotive ECU boards where board area is constrained.
Active production — sourced per RFQ
No direct pin-compatible replacement is listed — the DSC1001 series is the active baseline.
