100 MHz HCSL reference — MEMS, not quartz
The DSC1124DE2-100.0000T: The HCSL output delivers a differential 0.7V swing typical for PCIe Gen1/2/3, SATA, and 100BASE-TX reference clocks — the same signal level a standard quartz oscillator would provide, but without the aging drift and shock sensitivity of a crystal.
Stability and temperature — ±25 ppm across commercial range
That holds the timing budget for a 100 MHz reference without external trim capacitors — the MEMS resonator's temperature compensation is on-die, not a board-level adjustment. For indoor equipment (servers, switches, test gear) this is a direct drop-in for a quartz XO with the same stability spec. The Enable/Disable function (pin 1 on the 6-VDFN) tri-states the output when pulled low, cutting supply current to 22 mA max. This is useful for clock gating in power-sensitive designs — the oscillator does not need a separate load switch.
Lifecycle and sourcing — active, no end-of-life flags
Tape & Reel packaging is standard for this series.
