Four clocks in one 5x3.2 mm package
The DSC400-1111Q0081KI1T packs four independent LVCMOS clock outputs — 27 MHz, 50 MHz, 25 MHz, and 12 MHz — into a single 5.00 mm x 3.20 mm 20-VFQFN package, replacing up to four discrete crystal oscillators on the BOM. It uses a MEMS resonator rather than a quartz crystal, which means better shock and vibration tolerance and faster start-up — useful if the board goes into a portable instrument or a panel-mount controller that sees occasional impact.
Industrial temp grade and supply flexibility
Rated for -40 to 85 °C, this oscillator fits outdoor telecom cabinets, factory-floor PLCs, and engine-bay modules where the ambient temperature swings beyond commercial limits. The supply voltage spans 2.25 V to 3.6 V, so it can run from a 3.3 V or 2.5 V rail without an extra regulator — one less part to place. Frequency stability is ±50 ppm across the full temperature and voltage range, tight enough for most UART, SPI, and Ethernet PHY reference clocks.
Active and available for new designs
Microchip lists the DSC400-1111Q0081KI1T as Active — no NRND or EOL notice — so it is safe to qualify into a new BOM today. The Enable/Disable function lets you gate the outputs for power savings without cycling the supply rail.
