What this quad-output MEMS oscillator does on your board
The DSC400-1133Q0079KE1 is a MEMS-based XO (Standard) oscillator that delivers four independent clock outputs from a single 20-VFQFN package: 100 MHz, 100 MHz, 66.666 MHz, and 25 MHz. Outputs are selectable between LVCMOS and LVDS levels, letting you drive both single-ended logic and differential pairs from the same device without a translator.
Supply rails and temperature range for your BOM
Operating from 2.25 V to 3.6 V, it spans the common 2.5 V and 3.3 V logic rails without an extra regulator — check your rail tolerance; the wide range covers most FPGA and SoC banks.
Housed in a 20-VFQFN with exposed pad, measuring 5.00 mm x 3.20 mm and 0.90 mm tall — the thermal pad needs a via array under it for proper soldering and heat sinking.
