Product details

Active production — where this MEMS oscillator sits in the cycle

50 MHz CMOS output is a direct drop-in for any digital logic that expects a single-ended clock — no level translation needed for 3.3V or 2.5V cores. The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails without an external regulator. ±10 ppm frequency stability is tighter than the typical ±25 ppm or ±50 ppm found on basic quartz oscillators — relevant for USB, Ethernet, or any serial link where accumulated bit errors scale with clock drift.

Package and footprint — 6-SMD no-lead

The 3.20 mm x 2.50 mm 6-SMD no-lead package is a standard MEMS oscillator footprint — same land pattern as many SiTime and Abracon parts.

Frequently asked questions

Is the DSC1121CE5-050.0000T AEC-Q100 qualified?

Yes — the Ratings field lists AEC-Q100. This oscillator passed the automotive-grade qualification flow: temperature cycling, ESD, and reliability stress per the standard.

Does the DSC1121CE5-050.0000T have a recommended replacement if obsolete?

No — the product status is Active, so no replacement is listed. If a future EOL notice appears, the base product number DSC1121 covers the same family; a different stability or temperature grade variant may serve as a drop-in.
