The DSC8122AI2-PROGRAMMABLE: The LVPECL signalling provides the low-jitter, high-slew-rate edge needed for clocking 10/25/40/100 GbE PHYs, PCIe reference clocks, and SerDes transceivers — the differential pair rejects common-mode noise on the PCB trace.
The disable current is low enough to leave the oscillator powered on the same rail as the downstream logic without a dedicated power switch.
The DSC8122AI2-PROGRAMMABLE is an active Microchip part.
