The DSC400-1111Q0044KI2 packs four independent 25 MHz LVCMOS outputs into one 5.00 x 3.20 mm QFN package — a single oscillator replaces four discrete cans on the board, saving layout space and reducing BOM line count.
Operating from 2.25 V to 3.6 V, this part works on both 2.5 V and 3.3 V rails without a separate LDO — one less component to qualify.
Yes. The supply range is 2.25 V to 3.6 V, so it works directly on a 2.5 V rail without an extra regulator.
Any DSC400 variant with the same 20-VFQFN package and pinout — the base product number DSC400 covers multiple frequency and stability options. Check the Microchip ordering guide for a part with your target output frequencies.
