Hi,

The DSL/JHL 6340/6540 chips mentioned on https://www.anandtech.com/show/11692/intel-to-discontinue-first-gen-thunderbolt-3-controllers , that one is sitting between laptop's CPU/PCH and laptop's Thunderbolt 3 ports, no?

What are the names of the Thunderbolt 3 chips used in the Thunderbolt 3 devices, both for a non-daisy chained TB3 device such as Promise Sanlink N1 and for a daisy-chained TB3 device such as Akitio Node Pro or Sonnettech Echo Express III-D?

Are there any examples today where a manufacturer has integrated Thunderbolt 3-to-PCIe chip and PCIe device chip in one piece of silicon yet?

Thanks

The Alpine Ridge and the new Titan Ridge series chips from Intel convert between (DisplayPort, PCI Express) and Thunderbolt protocols, in both directions. Ie. you might be feeding DisplayPort and PCI Express lanes into it and then the output is a Thunderbolt signal. Or their input might be Thunderbolt and the output might be a bunch of DisplayPort and PCI Express signals.

One more kind of chip is relevant here, the Texas Instruments TPS65982 /TPS65983 which handles a physical USB C connection and negotaties with the device at the other end of the connection what the connection will be used for. One of the usages is Thunderbolt 3.

Let me know if you have any more questions.

I don't think anyone has made their own Thunderbolt chip yet. I believe this is something Intel has meant to allow but hasn't happened yet?
Intel to make Thunderbolt 3 royalty-free in bid to spur adoption

Thunderbolt hosts and peripherals (daisy chained and non-daisy chained) use the same Thunderbolt chips. The product can choose what to do with the ports provided by the Thunderbolt chip.
