Overview
The USB5533B hub is a 3-port, low-power, configurable Hub Controller fully compliant with the
USB 3.0 Specification
2.
The USB5533B supports 5 Gbps SuperSpeed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS) and
1.5 Mbps Low-Speed (LS) USB signaling for complete coverage of all defined USB operating speeds.
All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors and all
required pull-down and pull-up resistors on D+ and D- pins. The over-current sense inputs for the downstream facing
ports have internal pull-up resistors.
The USB5533B hub includes programmable features such as:
•
MultiTRAK
TM
Technology
(USB 2.0): implements a dedicated Transaction Translator (TT) for each port. Dedi-
cated TTs help maintain consistent full-speed data throughput regardless of the number of active downstream
connections.
•
PortSwap
(USB 2.0): allows direct alignment of USB signals (D+/D-) to connectors to avoid uneven trace length
or crossing of the USB differential signals on the PCB.
•
PHYBoost
(USB 2.0): enables 4 programmable levels of USB signal drive strength in downstream port transceiv-
ers. PHYBoost will also attempt to restore USB signal integrity.
As shown on the
Product Identification System
page, two USB5533B firmware versions are available: “-5000” and “-
6080”. These options differ in the following ways:
• The Dynamic Charging Port feature and related DYNCPDIS_N pin function are only available on the -6080
device. Refer to
Section 5.1.3, "Dynamic Charging Port (6080 Only)"
for additional details.
• The TRST/DYNCPDIS_N/UCS_SMBALERT_N pin buffer type is “IPU” in the -6080 device and “I” in the -5000
device. Refer to
Pin Information on page 7
for additional details.
• The Global Suspend power consumption has been significantly lowered in the -6080 device. Refer to
Section 6.3,
"Power Consumption"
for additional details.

Configurable Features
The USB5533B hub controller provides a default configuration that is sufficient for most applications. When initialized
in the default configuration, the following features may be configured:
•
•
•
•
•
Downstream non-removable ports, where the hub will automatically report as a compound device
Downstream disabled ports
Downstream port power control and over-current detection on a ganged or individual basis
USB signal drive strength
USB differential pair pin location
The USB5533B hub controllers can alternatively be configured by OTP or as an SMBus slave device. When configured
by an OTP or over SMBus, the following configurable features are provided:
• Support for compound devices on a port-by-port basis
• Selectable over-current sensing and port power control on an individual or ganged basis to match the circuit board
component selection
• Customizable vendor ID, product ID, and device ID
• Configurable delay time for filtering the over-current sense inputs
• Indication of the maximum current that the hub consumes from the USB upstream port
• Indication of the maximum current required for the hub controller
• Custom string descriptors (up to 30 characters): Product, manufacturer, and serial number
当今的计算机外部设备，都在追求高速度和高通用性。为了满足用户的需求，以Intel为首的七家公司于1994年推出了USB（Universal Serial Bus，通用串行总线）总线协议，专用于低、中速的计算机外设。目前，USB端口已成为微机主板的标准端口；而在不久的将来，所有的微机外设，包括键盘、鼠标、显示器、打印机、数字相机、扫描仪和游戏柄等等，都将通过USB与主机相连。
