Four clocks from one MEMS die
The DSC400-1111Q0110KE1T packs four independent LVCMOS clock outputs — 12 MHz, 15 MHz, 40 MHz, and 13 MHz — into a single 5.00 mm × 3.20 mm package. That replaces four quartz cans and their associated load caps, freeing board area and reducing the BOM line count by three.
Where the ±50 ppm stability fits
For a 12 MHz carrier, that is a ±600 Hz window — tight enough for UART baud-rate generation and most MCU clock trees, but marginal for precision GPS disciplined oscillators or Ethernet 1588 timing. The commercial temperature grade means this part is suited for indoor PCB assemblies — office equipment, telecom line cards, consumer IoT gateways. Not rated for under-hood or outdoor pole-mount without active thermal management.
Active lifecycle, no redesign pressure
New designs can proceed without a near-term migration plan. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external level translator.
