Product details

The supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without a separate regulator. CMOS output drives standard logic inputs directly; the 90 MHz frequency suits high-speed serial interfaces (e.g., Ethernet PHY reference clocks, CAN-FD controllers) or processor core timing where a quartz oscillator would need a larger footprint.

Housed in a 6-SMD, no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The MEMS resonator starts up faster than a quartz crystal — no long stabilization wait in the power-on sequence.

Frequently asked questions

What is the closest pin-compatible alternative to DSC1121DL5-090.0000?

Within the DSC1121 series, other frequency variants share the same 6-SMD no-lead footprint and pinout. For a different frequency at the same supply and temperature grade, the base product number DSC1121 covers the family. No direct second-source from another manufacturer is listed.
