Product details

MEMS oscillator for 33.333 MHz clock trees

The DSC1033DI1-033.3330 is a MEMS-based XO (Standard) oscillator delivering a 33.333 MHz CMOS output from a 3.3V supply rail — a drop-in replacement for quartz oscillators in applications where shock and vibration tolerance matter.

Package and board-fit details

Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts where height is constrained. Surface-mount mounting with a no-lead design means the solder joints are under the package body; the PCB landing pattern must match the recommended footprint in the datasheet to avoid tombstoning or insufficient fillet.

Frequently asked questions

Where can I buy DSC1033DI1-033.3330?

This part is sourced to order through independent distribution.

Can DSC1033DI1-033.3330 be replaced by a standard quartz oscillator?

Functionally yes — it is a MEMS-based XO that outputs a standard CMOS clock at 33.333 MHz. However, the MEMS resonator offers better shock and vibration resistance than quartz, and the package footprint (2.50 mm × 2.00 mm, 4-SMD no-lead) is specific; a quartz oscillator with the same footprint and electrical ratings would be a direct swap.
