PTN3222CUKZ

PTN3222CUKZ is a 1-port eUSB2 to USB2 redriver IC that performs translation between eUSB2 and USB2 signalling schemes. It is meant to be used in systems that have a eUSB2 interface on one side and USB2 interface on the other side. It supports a host repeater, device repeater, or dual-role repeater function. This implements Repeater mode (eUSB2 to USB2 redriver) and it supports Link Power management features. It is targeted to be USB2 compliant and eUSB2 conformant. It supports all three speeds/data rates low speed (1.5 Mbps), full speed (12Mbps), and high speed (480Mbps). This provides a target I²C register interface to initialize the required functionality and features as per the platform application's need. The I²C target address is selectable using a quaternary input pin. The RST-N pin is used to reset the IC without power cycling. Application includes eUSB2 to USB2 repeater function in platforms, host only repeater, device only repeater, dual role repeater.
