Overview
XR22414 USB 2.
0 4-Port MTT Hub General Description The XR22414 is a USB 2.
0 4-port hub using multiple transaction translators (MTT) for highest possible bandwidth capability.
The upstream USB interface has an integrated USB 2.
0 PHY and device controller that is compliant with both Hi-Speed (480Mbps) and Full-Speed (12Mbps) and downstream PHY supporting Hi-Speed, Full-Speed and Low-Speed (1.
5Mbps) on each of the 4 downstream ports.
The XR22414 provides two power modes, ganged or individual power control as well as global or individual over-current sensing modes.
The XR22414 operates from a single 5V or 3.
3V power input.
When powered by 5V, internal regulators provide a 3.
3V output which may be connected to VCC33 power input pins as well as external circuitry.
In turn a second internal regulator provides a 1.
8V output from the 3.
3V input.
This 1.
8V output may be connected to VCC18 power input pins.
Individual port activity and overall hub activity indicators provide status outputs for e...
