XR22414 USB 2.0 4-Port MTT Hub General Description FEATURES The XR22414 is a USB 2.0 4-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 and Individual port and hub activity LED device controller that is compliant with both Hi-Speed (480Mbps) and indicators Full-Speed (12Mbps) and downstream PHY supporting Hi-Speed, Individual or ganged port power enables Full-Speed and Low-Speed (1.5Mbps) on each of the 4 downstream Individual or global overcurrent sensing ports. Single 5V or 3.3V power supply Single 12MHz Crystal The XR22414 provides two power modes, ganged or individual power 48-pin TQFN and LQFP package options control as well as global or individual over-current sensing modes. APPLICATIONS The XR22414 operates from a single 5V or 3.3V power input. When USB port expansion powered by 5V, internal regulators provide a 3.3V output which may POS Terminals be connected to VCC33 power input pins as well as external circuitry. Test Instrumentation In turn a second internal regulator provides a 1.8V output from the Factory Automation and Process Controls 3.3V input. This 1.8V output may be connected to VCC18 power input Industrial Applications pins. Individual port activity and overall hub activity indicators provide Ordering Information - Back Page status outputs for external LEDs.
