USB Type-C插座,插头和电缆和现有的USB毗连相比,提供更小更薄和更可靠的毗连.USB Type-C办理方案目标应用在各种平台如条记本电脑,PC,智能手机,平板电脑等.本京电港论坛文章先容了USB Type-C主要特点,框架图和USB Type-C办理方案主要特点,系统级框架图和系统级功能框架图,以及USB CD/PD充电器框架图,电路原理图纸和质料清单,USB CD/PD PHY主/从框架图,电路原理图纸和质料清单以及USB CD/PD主/从框架图,电路原理图纸和质料清单. The USB Type-C receptacle, plug and cable provide a smaller, thinner and more robust alternative to existing USB interconnect. This new solution targets use in a variety of platforms, ranging from notebooks, PCs and monitors to smartphones and tablets, where existing Standard-A and Micro-AB receptacles are deemed too large, difficult to use, or inadequately robust. The USB Type-C plug enhances ease of use by being pluggable in either upside-up or upside-down directions and in either direction between host and devices.Determination of this hosttodevice relationship is accomplished through a Configuration Channel(CC)that is connected through the cable. These various solutions demonstrate the capabilities of the lattice device as USB 3.1 Power Delivery and Type-C ASSP. The solution include a DRP (dual-role port) function, hence it can be used as both DFP/Host/Source and UFP/Device/Sink after role resolution.One of the most important features of USB Type-C is the reversible nature of the connector and plug. This design also provides the provision to control a Super Speed switch required for data channel alignment/orientation management. Lattice PD controller can control both the SS (Super Speed Switch) and the HS (High Speed Switch) providing a seamless interface with Type C connector without any intervention from the main processor. The USB PD specifications have another exciting functional extension using the Type-C connector known as Alternate Modes. Lattice PD controller provides support for Structured VDM (Vendor Defined Messages)to handle these alternate modes like VESA Display Port over Type-C. USB Type-C主要特点: • Three solutions cover majority of USB Type-C Power Delivery (PD) and Cable Detect (CD) applications: USB Type-C器件表: USB Type-C enables products to provide faster charging, faster downloads and support other standards such as DisplayPort and MHL over Type-C. Lattice Type-C solutions provide Cable Configuration (CC), Power Delivery (PD) communication required to unlock these benefits. Some parts include integrated switches to simplify the implementation of video output. USB Type-C办理方案主要特点: CD/PD for charger uses part of the modules explained in the Module Level Diagram of Lattice USB 3.1 Type-C Solution section and 8 Bit controller based implementation as explained in the Lattice USB 3.1 Type-C Solution with Micro-controller (MICO8) section. CD/PD PHY for hosts/devices has the PHY (see the PHY section) implemented in Lattice Device and PD Protocol implemented in Application Processor as explained in the Lattice USB 3.1 Type-C Solution with an Application Processor section. For CD/PD for hosts/devices, refer to the Module Level Diagram of Lattice USB 3.1 Type-C Solution section. The Lattice USB Type-C solution is designed to provide bidirectional configuration channel signals (CC1/CC2) to the Type-C connector. The solution also provides VBUS power circuitry control signal and Super- Speed (SS) switch control signals.
