Product details

Quad-output MEMS oscillator for clock-tree consolidation

The DSC400-3331Q0097KE1T is a four-output MEMS-based XO delivering one 16 MHz and three 50 MHz clock signals from a single 5.0 mm × 3.2 mm 20-VFQFN package — consolidating what would otherwise require four discrete oscillators or a clock generator plus external crystals. Each output can be independently configured as LVCMOS or LVDS, letting the same device drive both a low-speed MCU clock (LVCMOS) and a high-speed SerDes reference (LVDS) without a level translator.

The 2.25 V to 3.6 V supply range covers common 2.5 V and 3.3 V rails without an external LDO — one less part to qualify.

Temperature grade and deployment fit

This suits indoor telecom switches, networking equipment, office automation, and test instrumentation where ambient stays within a conditioned space.

Frequently asked questions

How can I order the DSC400-3331Q0097KE1T and check current availability?

Submit an RFQ through this page. The part is Active and sourced through independent distribution — we confirm availability and pricing per your BOM quantity at quote time. No stock-holding claim is made here; the quote reflects real-time supply.

Does the DSC400-3331Q0097KE1T have an enable/disable function?

Yes, the function is Enable/Disable. Pulling the OE pin low tri-states the outputs, which lets you gate the clock tree during system sleep without an external load switch.

What is the difference between DSC400-3331Q0097KE1T and DSC400-3331Q0097KE1?

The suffix 'T' indicates Tape & Reel (TR) packaging. The 'KE1' variant without the 'T' suffix is typically supplied in a different carrier — tube or tray — but the electrical specifications are identical. Confirm the reel quantity and carrier format with your RFQ.

Is the DSC400-3331Q0097KE1T RoHS compliant?

RoHS compliance is standard for the DSC400 series from Microchip. The 20-VFQFN package is lead-free and compatible with lead-free reflow profiles. No separate RoHS certificate is required for this order code.
