XR22417 USB 2.0 7-Port Hub Description FEATURES The XR22417 is a USB 2.0 7-port hub using Multiple Transaction USB 2.0 compliant interface Translators (MTT) for highest possible bandwidth capability. Multiple transaction translators (MTT) Regulated +3.3V output power The upstream USB interface has an integrated USB 2.0 PHY Individual port and hub activity and device controller that is compliant with both hi-speed (480 LED indicators Mbps) and full-speed (12 Mbps). The downstream PHY supports Individual power enables (LQFP-64) hi-speed, full-speed and low-speed (1.5 Mbps) on each of the 7 Individual overcurrent sensing (LQFP-64) downstream ports. Individual port activity and overall hub activity Single 5V power input indicators provide status outputs to control external LEDs for Single 12 MHz Crystal each port. An external EEPROM may be used with the APPLICATIONS XR22417 to change selected USB descriptors including the USB port expansion USB vendor and product IDs, the number of downstream ports Docking stations and device serial number. Overcurrent protection and power POS terminals control for each downstream port is available in the LQFP-64 Test instrumentation package. The XR22417 operates from a single 5V power input. Factory automation and process controls Internal regulators provide a 3.3V output which may be connected to Industrial applications 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.
