Six frequencies in one 5.0×3.2 mm MEMS oscillator
The DSC400-1111Q0019KI2T packs six independent LVCMOS clock outputs from a single MEMS resonator: 25 MHz, 50 MHz, 125 MHz, 150 MHz, 100 MHz, and 156.25 MHz. That replaces up to six discrete XOs on the board, saving real estate and BOM line count.
Active production — no EOL clock ticking
Microchip lists this part as Active. For a production line that needs multi-year supply, this is a clean bill of health.
Supply voltage tolerance and temperature grade
Runs from 2.25 V to 3.6 V, so it sits on a 2.5 V or 3.3 V rail without a separate regulator. The 20-VFQFN Exposed Pad package (5.00 mm × 3.20 mm, 0.90 mm height) needs a thermal pad on the PCB for heat sinking. The exposed paddle also ties to the ground plane, which helps with EMI containment on the output traces.
