Description
The XR22417 evaluation board is for the Exar USB 2.0 7-Port hub in both the 64 pin LQFP and 48 pin LQFP packages. Thismanual is intended to guide users to use various functions and configurations of the hub device.The XR22417 is a USB 2.0 7-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 (480 Mbps) and full-speed (12 Mbps). The downstream PHY supports hi-speed, full-speed and low-speed (1.5 Mbps) on each of the 7 downstream ports. Individual port activity and overall hub activity indicators provide status outputs to control external LEDs for each port. An external EEPROM may be used with the XR22417 to change selected USB descriptors including the USB vendor and product IDs, the number of downstream ports and device serial number. The XR22417 provides different power modes, ganged or individual power control as well as global or individual overcurrent sensing modes. In individual power control each port has an overcurrent input designed to be used with a current sensing device and a power control output that can remove power from the attached device on that port. The XR22417 operates from a single 5V power input. Internal regulators provide a 3.3V output which may be connected to VCC33 power input pins. 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
