USB5742-I/2G規(guī)格書詳情

USB5742-I/2G屬于集成電路(IC)的控制器。由微芯科技股份有限公司制造生產(chǎn)的USB5742-I/2G控制器該系列產(chǎn)品主要用于在采用不同通信協(xié)議和/或信令方法的端點之間提供信息連接。示例包括將 I2C 總線連接到 UART,將 USB 連接到 I2C、SPI、以太網(wǎng)或 UART、以太網(wǎng) MAC 和 PHY 等的器件。此外,還包括用于通過為點對點通信設計的接口建立多路連接的器件,例如 USB 集線器控制器。

General Description

The Microchip USB5742 hub is low-power, OEM configurable, USB 3.2 Gen 1 hub feature controller with 2 downstream

ports and advanced features for embedded USB applications. The USB5742 is fully compliant with the Universal Serial

Bus Revision 3.2 Specification and USB 2.0 Link Power Management Addendum. The USB5742 supports 5 Gbps

SuperSpeed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) USB downstream

devices on all enabled downstream ports.

The USB5742 supports the legacy USB speeds (HS/FS/LS) through a dedicated USB 2.0 hub feature controller that is

the culmination of five generations of Microchip hub feature controller design and experience with proven reliability,

interoperability, and device compatibility. The SuperSpeed hub feature controller operates in parallel with the USB 2.0

controller, decoupling the 5 Gbps SS data transfers from bottlenecks due to the slower USB 2.0 traffic.

The USB5742 supports downstream battery charging. The USB5742 integrated battery charger detection circuitry supports

the USB-IF Battery Charging (BC1.2) detection method and most Apple devices. The USB5742 provides the battery

charging handshake and supports the following USB-IF BC1.2 charging profiles:

? DCP: Dedicated Charging Port (Power brick with no data)

? CDP: Charging Downstream Port (1.5A with data)

? SDP: Standard Downstream Port (0.5A with data)

? Custom profiles loaded via SMBus or OTP

Additionally, the USB5742 includes many powerful and unique features such as:

PortSwap, which adds per-port programmability to USB differential-pair pin locations. PortSwap 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, which provides programmable levels of Hi-Speed USB signal drive strength

in the downstream port transceivers. PHYBoost attempts to restore USB signal integrity

in a compromised system environment. The graphic on the right shows an example of

Hi-Speed USB eye diagrams before and after PHYBoost signal integrity restoration. in

a compromised system environment

VariSense, which controls the USB receiver sensitivity enabling programmable levels of USB signal receive sensitivity.

This capability allows operation in a sub-optimal system environment, such as when a captive USB cable is used.

The USB5742 can be configured for operation through internal default settings. Custom OEM configurations are supported

through external SPI ROM or OTP ROM. All port control signal pins are under firmware control in order to allow

for maximum operational flexibility, and are available as GPIOs for customer specific use.

The USB5742 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature range. An internal

block diagram of the USB5742 is shown in Figure 2-1.
