The DSC400-0101Q0115KI1T: This is a MEMS-based XO that puts out two LVCMOS clocks: 12 MHz on output 1 and 3.072 MHz on output 2. The MEMS resonator means no quartz blank, no external load capacitors, and no crystal start-up time — it's powered up and oscillating within microseconds of the enable pin going high. Supply voltage spans 2.25 V to 3.6 V, so it runs from a 2.5 V or 3.3 V rail without a separate LDO.
Yes, if the board expects a 12 MHz LVCMOS clock input. Unlike a quartz crystal, this MEMS XO does not require external load capacitors — it generates a full-swing LVCMOS output directly. The second output (3.072 MHz) is a bonus clock that can drive a separate peripheral or a UART baud-rate generator.
No. Because the resonator is a MEMS structure sealed inside the package, the output is already a rail-to-rail LVCMOS signal. No external load caps, no feedback resistor — just connect the supply and the enable pin.
±50 ppm over the full -40°C to +85°C range and supply voltage variation. That stability class suits most Ethernet PHYs, MCU clock inputs, and USB interfaces without needing a separate temperature-compensation circuit.
