Six clocks from one 20-VFQFN package
The DSC400-1111Q0019KI2 is a MEMS-based XO (Standard) that generates six independent LVCMOS clock outputs from a single 20-VFQFN package with an exposed pad — 25 MHz, 50 MHz, 125 MHz, 150 MHz, 100 MHz, and 156.25 MHz.
Supply flexibility and output control
The supply voltage spans 2.25 V to 3.6 V, so the same oscillator can run from a 2.5 V or 3.3 V rail without a separate level translator on the output side — the LVCMOS swing tracks the supply. An Enable/Disable function on the package lets firmware gate the outputs during low-power sleep states, pulling the oscillator into a high-impedance state without a downstream clock buffer.
Board-fit and reflow considerations
The 20-VFQFN with exposed pad measures 5.00 mm x 3.20 mm and sits 0.90 mm tall — the exposed pad needs a thermal via array under the package to pull heat into the ground plane; without it the junction temperature rises faster during reflow and the MEMS die sees higher stress.
