Product details

Quad-output MEMS oscillator for timing consolidation

This replaces up to four discrete crystal oscillators, saving board area and reducing BOM line count.

Supply voltage and frequency stability for timing margin

Operating from 2.25 V to 3.6 V, the part covers common logic supply rails (2.5 V, 3.3 V) without an external regulator.

20-VFQFN package layout and thermal management

Housed in a 5.00 mm x 3.20 mm, 20-lead VFQFN with an exposed pad, the DSC400-3331Q0098KI1T requires a thermal via array under the pad to achieve the rated power dissipation. The 0.90 mm height suits tight card-edge clearance in mezzanine or blade-style boards.

Frequently asked questions

How can I order the DSC400-3331Q0098KI1T or check availability?

The DSC400-3331Q0098KI1T is an active Microchip part. Submit an RFQ with your target quantity and delivery window; we source through independent distribution and confirm pricing and lead time per order. No stock-holding claim is made on this page.

What are the exact output frequencies of the DSC400-3331Q0098KI1T?

The device provides four outputs: one at 12 MHz and three at 50 MHz. Each output can be independently configured as LVCMOS or LVDS.

Can the DSC400-3331Q0098KI1T replace a quartz crystal oscillator?

Yes — it is a direct functional replacement for a standard XO (oscillator) in the same footprint, but with MEMS technology. The MEMS resonator eliminates quartz start-up issues and offers better shock/vibration tolerance. Verify the 20-VFQFN footprint matches your existing layout before substitution.

Is the DSC400-3331Q0098KI1T suitable for outdoor or industrial environments?

Yes. The -40°C to +85°C operating temperature range covers outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics. The MEMS construction also resists the vibration and thermal cycling common in those settings.
