NXP Semiconductors PTN3222 1-Port eUSB2 to USB2 Redrivers

NXP Semiconductors PTN3222 1-Port eUSB2 to USB2 Redrivers perform translations between eUSB2 and USB2 signaling schemes. The NXP redrivers are used in systems that have a eUSB2 interface on one side and a USB2 interface on the other side. The devices support a host repeater, device repeater, or dual role repeater function.
