Yini i-I-I-I-USB4 entsha sha?

 

KokubiliI-USB 3.1futhiI-USB 3.2yethulwe ukukhulisa umkhawulokudonsa, kanye nezinhloso zokwakhiwa kwe-I-I-I-USB4hlala ungashintshiwe. Kodwa-ke, ukukhishwa kwale ncazelo futhi ukuhlanganisa i-Uhlobo C lwe-USBi-ecology futhi inciphise ukudideka kwabasebenzisi bokugcina.

 

Although the new I-I-I-USB4 standard introduces a new underlying protocol, it is still compatible with the existing USB3.2, USB2.0 and Thunderbolt 3. I-I-I-USB4 will adopt a dual-channel dual-simplex architecture, which doubles the transmission bandwidth of Type-C, with a transmission rate of at least 20Gbps and optional 40Gbps. The maximum transmission rate is twice that of the previous generation I-USB 3.2. For certified interfaces and cables Two different logos will also be provided. For 40GbpsI-I-I-USB4, the encoding method is still 128b/132b used by I-USB 3.2, while 20Gbps will use 64b/66b. A I-I-I-USB4 source provides at least 7.5W of power (5V, 1.5A) per port.

 

Ngaphezu kwalokho,I-I-I-USB4 adds tunnel support to support PCie and DisplayPort1.4a, thereby achieving multi-protocol compatibility on a single physical interface. Brad Saunders pointed out that most computers equipped with I-I-I-USB4 will be compatible with Thunderbolt 3, but for mobile phone manufacturers, this support should not be added. As for software support, it is known that the Linux 5.6 system already supports I-I-I-USB4, and the I-I-I-USB4 driver for Microsoft Windows is said to be still under development.

Cypress announced in March 2020 the Type-C controllers for next-generation desktop and mobile computers, EZ-PD CCG6DF and EZ-PD CCG6SF. Kokubilicontrollers are single-chip solutions and are compatible with I-USB 3.2/4.

I-CCG6DF / CCG6SF isekela izimbobo ezimbili (i-DRP) futhi izokweseka ngokuphelelePD3.0Ukucaciswa. Lolu hlelo lufaka phakathi i-64KB yesitoreji se-flash kanye ne-96KB yesitoreji seROM, futhi isekela ukuqalisa okuphephile nokuhluleka kwe-firmware.
