Outputs are HCSL or LVCMOS selectable per bank, with a global Enable/Disable pin that pulls the outputs to high-impedance when deasserted — useful for system-level power gating or test isolation. ## Supply-range flexibility and package footprint The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails without an external LDO — one BOM line serves either power domain. The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm, 0.90 mm height) requires a thermal-land pattern on the PCB — the centre pad must be soldered to a ground-plane via array for rated thermal performance. Supplied in tape & reel, compatible with standard pick-and-place equipment;.","metaTitle":"DSC400-4111Q0112KE2T MEMS Oscillator – 25MHz &","metaDescription":"Microchip DSC400-4111Q0112KE2T quad-output XO: three 25MHz + one 100/156.25MHz, HCSL/LVCMOS, ±25ppm stability, 2.25V–3.6V supply, 20-VFQFN.
