MEMS oscillator — 33.333 MHz, CMOS, standby
The DSC1033DI2-033.3330T: The ±25 ppm frequency stability holds across the full -40 to 85°C industrial band — enough margin for a 100BASE-TX Ethernet reference clock or a USB 2.0 full-speed controller, where the ppm budget includes the downstream PLL jitter. On wake, the MEMS resonator starts faster than a quartz equivalent; no crystal start-up delay to budget in the firmware.
Quantities are lot-specific — confirmed at RFQ. No stock-holding claim; sourced per order against the BOM quantity.
Package and footprint — 2.5 x 2.0 mm 4-SMD
4-SMD, No Lead package, 2.50 mm x 2.00 mm body, seated height 0.90 mm max. The 0.098" x 0.079" footprint is shared with many MEMS and quartz oscillators in the 2.5 x 2.0 mm format — a layout designed for a SiTime or Epson equivalent can often accept this part with no pad change, but confirm the pinout against the datasheet before committing.
