High performance, low-power, small footprint hub controller IC with 2, 3, 4, or 7 downstream ports (indicated by the “x” in the part number)

Fully compliant with the USB 2.0 specification

Enhanced OEM configuration options available through either a single serial I2C® EEPROM, or SMBus slave port

MultiTRAK - High-performance multiple transaction translator which provides one transaction translator per port

PortMap - Flexible port mapping and disable sequencing

PortSwap - Programmable USB differential-pair pin locations ease PCB design by aligning USB signal lines directly to connectors

PHYBoost - Programmable USB signal drive strength for recovering signal integrity using 4-level driving strength resolution

Full power management with individual or ganged power control of each downstream port

Fully integrated USB termination and pull-up/pulldown resistors

Supports a single external 3.3 V supply source; internal regulators provide 1.8 V internal core voltage

Onboard 24 MHz crystal driver, ceramic resonator, or external 24/48 MHz clock input

Customizable vendor ID, product ID, and device ID
