The DSC1001BI2-012.2880 is a MEMS-based XO (Standard) from Microchip’s DSC1001 series, delivering a 12.288 MHz CMOS output with ±25 ppm frequency stability. Its 1.8V to 3.3V supply range lets it drop into either a 1.8V or 3.3V clock domain without a level translator — useful when the same BOM must span multiple voltage rails. The 4-SMD no-lead package (5.00 mm × 3.20 mm, 0.90 mm seated height) is a standard footprint for MEMS oscillators, so the board layout is straightforward — no special fan-out or via-in-pad required.

Frequently asked questions
Is the DSC1001BI2-012.2880 compatible with a 1.8V supply?
Yes. The supply voltage range is 1.8V to 3.3V, so it runs directly from a 1.8V rail without an external regulator or level translator. The CMOS output swings rail-to-rail, so the downstream logic sees a clean 1.8V swing.
What is the difference between the DSC1001BI2-012.2880 and the DSC1001CI2-012.2880?
The difference is the operating temperature range. Both share the same 12.288 MHz frequency, ±25 ppm stability, CMOS output, and 1.8V–3.3V supply. Choose the CI2 if the ambient temperature exceeds 85°C.
