Product details

MEMS oscillator, four clocks, one footprint

Frequency stability is ±25 ppm across the -20°C to 70°C commercial range — tight enough for a 100BASE-TX Ethernet PHY reference or a USB 2.0 clock without external trimming.

Supply flexibility and enable control

Runs from 2.25V to 3.6V, so it sits on a 2.5V or 3.3V rail without a separate LDO. The Enable/Disable function lets firmware gate the unused outputs during sleep modes. The 5.00 mm x 3.20 mm body with 0.90 mm height fits tight mezzanine card stacks; the exposed pad under the QFN needs a thermal via array to keep the MEMS die within the temperature spec.

Active status – no LTB window to chase

Frequently asked questions

Where can I buy DSC400-3331Q0097KE2 and how do I get a price?

This part is Active and orderable. Submit an RFQ with your target quantity and we will confirm current pricing and lead time through our sourcing desk. No stock-holding claim — quoted to order.

What is the closest pin-compatible alternative to DSC400-3331Q0097KE2 in the DSC400 family?

No official second-source or direct pin-compatible alternative is listed by Microchip. The DSC400 series shares the same 20-VFQFN footprint across frequency configurations, but the output frequency mix is programmed at the factory — a different order code will not produce the same 16/50/50/50 MHz set.
