Product details

The supply range spans 2.25V to 3.6V, meaning the same order code covers 2.5V and 3.3V logic rails — no need to qualify a separate voltage variant for each rail.

Frequency stability and temperature grade

For a 24.576 MHz clock, ±25 ppm translates to a maximum drift of about 614 Hz — well within the capture range of a standard Ethernet PHY or USB controller without re-centering the PLL. The MEMS construction also means the oscillator starts up faster than a quartz equivalent — no crystal start-up time to budget into the power-on sequence.

Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.

Frequently asked questions

How can I order the DSC1121BI2-024.5760 or request a quote?

The DSC1121BI2-024.5760 is an active Microchip part. Submit an RFQ with your target quantity and target price; we source through independent distribution and confirm availability and current pricing at quote time. No stock-holding claim — every order is quoted to your BOM line.

What is the frequency tolerance of the DSC1121BI2-024.5760?

This is the total variation including temperature, supply voltage, and aging — no separate initial tolerance spec is listed.

Does the DSC1121BI2-024.5760 support a 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so both 2.5V and 3.3V rails are within spec. No external regulator or level translator is needed when moving between these common logic voltages.

Is the DSC1121BI2-024.5760 a direct replacement for a quartz oscillator?

Functionally yes — it is a drop-in XO replacement with CMOS output in a standard 6-SMD footprint. The MEMS resonator is more shock-tolerant and starts up faster than quartz, but the electrical interface (supply, output, enable) is identical to a quartz oscillator of the same package and pinout.

What is the difference between the DSC1121BI2 and the DSC1121CI2?

The evidence does not list a DSC1121CI2 variant. The DSC1121 series includes multiple stability and temperature options; the BI2 suffix in this order code indicates ±25 ppm stability over -40°C to 85°C. Confirm the full order code against your BOM — the CI2 may carry a different stability or temperature grade.
