Product details

Dual-frequency MEMS XO for timing-tree consolidation

The DSC400-0101Q0114KE1T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent LVCMOS clock outputs: 12 MHz and 12.288 MHz. This dual-frequency capability lets a single oscillator replace two discrete crystal oscillators on the board, saving footprint and reducing BOM line count. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external regulator.

Package and layout considerations for the 20-QFN

Housed in a 20-VFQFN exposed pad package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.50 mm pitch QFN demands careful solder-paste stencil design to avoid bridging; a 4-mil stencil with 1:1 aperture-to-land ratio is a common starting point. No special high-speed layout rules beyond standard 50-ohm trace impedance for the LVCMOS outputs if the trace length exceeds 1 inch.

Frequently asked questions

What are the two output frequencies of the DSC400-0101Q0114KE1T?

Output 1 is 12 MHz; Output 2 is 12.288 MHz. Both are LVCMOS-level signals with enable/disable control.

Does the DSC400-0101Q0114KE1T have an enable/disable feature?

Yes, the function is Enable/Disable. When disabled, the outputs go into a high-impedance state, allowing the oscillator to be gated for power savings or test isolation.

Is the DSC400-0101Q0114KE1T a direct replacement for a standard quartz XO?

This is a MEMS-based XO, not a quartz crystal oscillator. It is a drop-in functional replacement for a dual-output quartz XO in the same package and with the same supply voltage, but the MEMS resonator has different aging and vibration characteristics — review the Microchip application note for MEMS timing if the board sees high mechanical shock or wide temperature swings beyond the rated -20°C to +70°C.
