Si53254A-01AM Automotive PCI Express Clock 1:4 Fanout Buffer

The Si53254A-01AM is a PCI Express Gen 1/2/3/4/5/6 1 : 4 fanout buffer supporting both 85 Ω and 100 Ω impedance. The device is AECQ-100 qualified for automotive grade2 (-40 to +105 °C) automotive infotainment ADAS and automated driving platforms. The low-power HCSL output drivers feature full internal termination, minimizing the number of external components required.
