Product details

Four 50 MHz clocks from one MEMS die

The DSC400-1111Q0034KI1T packs four independent LVCMOS outputs, each running at 50 MHz, from a single MEMS resonator — no separate crystal or PLL for each clock rail. Supply voltage spans 2.25 V to 3.6 V, so the same part works on a 2.5 V or 3.3 V rail without a level translator on the output.

Industrial temp grade and board-fit constraints

The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm) requires a thermal land on the PCB for heat sinking; the 0.035-inch (0.90 mm) height keeps it compatible with standard mezzanine card spacing.

Active lifecycle — no obsolescence watch

Frequently asked questions

What is the exact frequency output of DSC400-1111Q0034KI1T?

All four outputs are 50 MHz LVCMOS — the part delivers four identical 50 MHz clock rails from a single MEMS resonator.
