Product details

Quad-output MEMS XO — three 25 MHz plus one 125 MHz

The DSC400-1111Q0085KE1 is a MEMS-based XO with four LVCMOS outputs: three at 25 MHz and one at 125 MHz. A single 20-VFQFN package replaces four discrete oscillators, reducing BOM count and layout area on the clock tree.

Commercial temperature grade, active production

Package and footprint — 20-VFQFN with exposed pad

Housed in a 5.00 mm × 3.20 mm, 20-lead VFQFN with an exposed thermal pad. The 0.90 mm height keeps it low-profile for mezzanine or card-edge assemblies. Supplied in tube; tape-and-reel availability should be confirmed at RFQ if pick-and-place volume is needed.

Frequently asked questions

Is the DSC400-1111Q0085KE1 compatible with a 2.5V supply?

Yes — the supply range is 2.25V to 3.6V, so it operates on a 2.5V rail without a separate regulator. The LVCMOS output levels track the supply voltage.

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

The DSC400 family shares the same 20-VFQFN footprint across multiple frequency plans. A direct cross would be another DSC400 order code with the same package and supply range but different output frequencies — confirm the output configuration against your clock tree before substituting.

Does the DSC400-1111Q0085KE1 come in tape and reel or tube?

The listed package is tube. Tape-and-reel packaging may be available through the same supply channel — specify your preference at RFQ so the sourcing team can confirm availability.
