Why this quad-output XO replaces three crystals
The DSC400-1111Q0111KI1 delivers three independent LVCMOS clock outputs from one 5.00 x 3.20 mm package — 25 MHz, 20 MHz, and 24 MHz — replacing three quartz crystals and their load capacitors on the BOM. Its 2.25 V to 3.6 V supply range lets it power from a 2.5 V FPGA bank or a 3.3 V clock-tree rail without a separate level translator, cutting one more IC from the board.
Active production status and package fit
Microchip lists the DSC400-1111Q0111KI1 as Active — production is ongoing, no NRND or last-time-buy window. The centre pad should be connected to ground plane with at least four vias to pull heat out of the die and keep the MEMS resonator within its frequency-stability spec.
