XR22417
USB 2.0 7-Port Hub
Description
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. Overcurrent protection and power
control for each downstream port is available in the LQFP-64
package. 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.
