USB2517I-JZX

The 7-Port Hub is a low power, OEM configurable, MTT (multi transaction translator) hub controller IC with 7 downstream ports for embedded USB solutions. The 7-port hub is fully compliant with the USB 2.0 Specification and will attach to an upstream port as a Full-Speed Hub or as a Full-/Hi-Speed Hub. The 7-Port Hub supports Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed Hub) downstream devices on all of the enabled downstream ports.

Applications

• LCD monitors and TVs
• Multi-function USB peripherals
• PC mother boards
• Set-top boxes, DVD players, DVR/PVR
• Printers and scanners
• PC media drive bay
• Portable hub boxes
• Mobile PC docking
• Embedded systems

Key features

• Hub Controller IC with 7 downstream ports
• High-performance multiple transaction translator MultiTRAK Technology provides one transaction translator per port
• Enhanced OEM configuration options available through either a single serial I2C EEPROM, or SMBus Slave Port
• 64-Pin (9x9 mm) QFN, RoHS compliant package
• Supports commercial (0℃ to +70℃) and industrial (-40℃ to +85℃) temperature ranges
• Low power operation
• Full Power Management with individual or ganged power control of each downstream port
• On-chip Power On Reset (POR)
• Internal 1.8V Voltage Regulator
• Fully integrated USB termination and Pull-up/Pulldown resistors
• On Board 24MHz Crystal Driver, Resonator, or External 24/MHz clock input
• USB host/device speed indicator. Per-port 3-color LED drivers indicate the speed of USB host and device connection - hi-speed (480 Mbps), fullspeed (12 Mbps), low-speed (1.5 Mbps)
• Enhanced EMI rejection and ESD protection performance
• Customizable Vendor ID, Product ID, and Device ID
• Select whether the hub is part of a compound device (When any downstream port is permanently hardwired to a USB peripheral device, the hub is part of a compound device.)
• Flexible port mapping and disable sequence. Ports can be disabled/reordered in any order to support multiple product SKUs. Hub will automatically reorder the remaining ports to match the Host controller's numbering scheme
• Programmable USB differential-pair pin location - Eases PCB layout by aligning USB signal lines directly to connectors
• Programmable USB signal drive strength. Recover USB signal integrity due to compromised system environments using 4-level driving strength resolution
• Select the presence of a permanently hardwired USB peripheral device on a port by port basis
• Configure the delay time for filtering the over-current sense inputs
• Configure the delay time for turning on downstream port power
• Indicate the maximum current that the 7-port hub consumes from the USB upstream port
• Indicate the maximum current required for the hub controller
• Support Custom String Descriptor up to 31 characters in length for: - Product String - Manufacturer String - Serial Number String
• Pin Selectable Options for Default Configuration - Select Downstream Ports as Non-Removable Ports - Select Downstream Ports as Disabled Ports - Select Downstream Port Power Control and Over-Current Detection on a Ganged or Individual Basis - Select USB Signal Drive Strength - Select USB Differential Pair Pin location
