USB2517-JZX-TR

Technical Specifications

Product Introduction

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 lead-free, RoHS compliant package
• 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/Pull down resistors
• On Board 24MHz Crystal Driver, Resonator, or External 24MHz 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), full-speed (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 OverCurrent Detection on a Ganged or Individual Basis Select USB Signal Drive Strength Select USB Differential Pair Pin location
