Why this MEMS oscillator exists for automotive clock trees
The DSC1001CL2-033.3333T delivers 33.3333 MHz with ±25 ppm stability across that band, so the CAN bus or the MCU PLL stays locked without a separate TCXO. The 1.8V to 3.3V supply range means this single part number covers both the 1.8V core rail and the 3.3V I/O rail on a mixed-voltage board — no need to qualify two oscillators.
Standby function for power-sensitive nodes
3.20 mm x 2.50 mm 4-SMD no-lead package (0.90 mm seated height) — a standard 2520 footprint that drops onto the same PCB land pattern as quartz oscillators from Epson, SiTime, or Abracon. Supplied on Tape & Reel — compatible with automated pick-and-place lines running 8 mm carrier tape.
