Quad-frequency MEMS oscillator for multi-rail timing
The DSC400-0111Q0116KI1 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering three fixed output frequencies: 12.288 MHz, 14.7456 MHz, and 11.2896 MHz — all in LVCMOS logic levels. With a supply voltage range of 2.25 V to 3.6 V, this oscillator can share a rail with a 3.3 V or 2.5 V logic bus without an external regulator.
The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal pad on the PCB for heat sinking — the exposed paddle must be soldered to a copper plane to keep the MEMS die within its operating junction temperature.
