XR22417

USB 2.0 7-Port Hub

Description

FEATURES

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.
