MEMS oscillator at 26 MHz — what swaps in the field
Supply voltage spans 1.8V to 3.3V, so it runs off a 1.8V core rail or a 3.3V I/O rail without a separate regulator — one part number covers both domains on the same BOM.
Automotive-grade qualification and temperature envelope
Supplied in Tape & Reel (TR) — the 'T' suffix on the order code. The 4-SMD no-lead package (3.20mm x 2.50mm, 0.90mm seated height) is a standard footprint shared across the DSC1001 family, so a pick-and-place program for one variant often works for others.
