33.333 MHz MEMS XO – industrial temp, ±25 ppm
The DSC1121BI2-033.3330 is a 33.333 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering CMOS output with ±25 ppm frequency stability across -40°C to 85°C. Its 2.25V to 3.6V supply range lets it run directly from 2.5V or 3.3V rails without an extra regulator — a clean fit for mixed-voltage clock trees.

6-SMD package – board-fit note
Housed in a 5.00 mm × 3.20 mm 6-SMD No Lead package, 0.90 mm seated height — the footprint matches standard 6-pin oscillator land patterns, so a quartz XO swap is a direct layout drop-in.
