Product details

8 MHz MEMS oscillator with ±25 ppm stability

Supply voltage spans 2.25V to 3.6V, covering 2.5V, 3.0V, and 3.3V logic rails without an intermediate regulator — the CMOS output swings rail-to-rail into a standard 15 pF load.

The part ships in Tape & Reel (TR) packaging, 6-SMD no-lead footprint, 3.20 mm x 2.50 mm body with 0.90 mm seated height — a standard MEMS oscillator footprint that drops onto a two-layer board without via-in-pad.

Maximum supply current is 22 mA at full load — the actual draw depends on the output frequency and load capacitance; at 8 MHz into 15 pF it typically runs well under that ceiling.

Frequently asked questions

Is the DSC1121CI2-008.0000T compatible with a 3.3V supply?

Yes — the supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. The CMOS output swings to the supply rail, so a 3.3V supply gives a 3.3V logic-level output.

What is the closest pin-compatible alternative to the DSC1121CI2-008.0000T?

The DSC1121 series includes multiple frequency and stability variants in the same 6-SMD footprint. For the same 8 MHz frequency, the DSC1121CI2-008.0000T is the ±25 ppm, -40°C to 85°C grade. A ±50 ppm grade (DSC1121CI2-008.0000) or extended temperature variant may also fit — confirm the BOM stability requirement before substituting.
