Four clocks, one footprint — what the DSC400 buys the board
The DSC400-3133Q0080KE2T is a MEMS-based XO that packs four independent output frequencies into a single 20-VFQFN package measuring 5.00 mm x 3.20 mm — that replaces four discrete quartz cans with one part, freeing up about 60% of the board area those cans would occupy. Outputs are configurable as LVCMOS or LVDS per the datasheet, so the same oscillator can drive a processor reference clock on one lane and a high-speed serial link on another without a level translator.
Supply rail tolerance and temperature grade
The supply range spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an intermediate regulator — useful when the board has a shared 3.3 V plane and the oscillator sits near a 2.5 V FPGA bank.
