anandtech 这篇文章显示 7000 系列的三款 tb 控制器都是 titan ridge 控制器,都支持 dp 1.4。6000 系列都是 alpine ridege,都只支持 dp 1.2。

Overall the Titan Ridge family of Thunderbolt 3 controllers consists of three parts: the JHL7540 and the JHL7340 chips for PCs, as well as the JHL7440 chip designed for peripherals. The JHL7340 and the JHL7540 support one and two TB3 ports, respectively, and work exactly like their Apine Ridge predecessors but with the addition of DisplayPort 1.4 functionality.

7000 系列有 3 款,JHL7540 和 JHL7340 都是给电脑用的,分别支持两个、一个 tb 口。JHL7440 给配件用,也支持两个 tb 口,作为扩展坞的控制器,它可以让扩展坞兼容 usb 协议。

There will be two host controllers, known as Maple Ridge JHL8540 and JHL8340, for use as host controllers in desktops, workstations, and laptops. We are told the package size and power requirements are essentially in-line with previous Titan Ridge TB3 controllers. The device controller, for use in docks, monitors, storage devices and such, is the Goshen Ridge JHL8440. All three of these controllers will be available by the end of the year.

针对雷电 4 发布了 3 款控制器,8000 系列,Maple Ridge。JHL8540、JHL8340 面向 host,JHL8440 面向 device。
