Four independent clock outputs from one MEMS resonator
The DSC400-1133Q0113KE2T delivers four independent output frequencies from a single MEMS resonator: 100 MHz, 156.25 MHz, 125 MHz, 125 MHz, and 25 MHz — the 125 MHz appears on two outputs, giving a total of four clock lanes from one package. Outputs are configurable as LVCMOS or LVDS, so the same oscillator can feed a FPGA reference clock on one lane and a SerDes or Ethernet PHY on another without a level translator.
Supply voltage range simplifies rail assignment
The 2.25 V to 3.6 V operating range covers both 2.5 V and 3.3 V rails — the same BOM line works across a mixed-voltage board without a dedicated regulator.
20-VFQFN package layout checklist
The 20-VFQFN exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height) requires a thermal via array under the pad for heat sinking and mechanical stability — the pad must be soldered to a copper plane on the top layer, with vias to inner ground layers.
