With the release of Intel Gen 11 Core, many manufacturers have released notebooks with Thunderbolt 4 interfaces. Now, according to AnandTech, Intel’s first standalone Thunderbolt 4 controller, Maple Ridge (JHL8540), is also shipping, which means hardware manufacturers can use the Thunderbolt 4 interface in non-11th Core products.

Intel announced the Thunderbolt 4 controller 8000 series in July this year, including the JHL8540 and JHL8340 host controllers for computer manufacturers and the JHL8440 device controller for accessory manufacturers.

The Intel Thunderbolt 4 Controller 8000 Series supports up to four Thunderbolt 4 interfaces. Accessory manufacturers can use this chip to produce 4-port Thunderbolt 4 docking stations (1 input, 3 outputs). In addition, the Thunderbolt 4 cable will be available in 0.2m, 0.8m, and 2m, with future versions of 5 to 50m to be released. The JHL8540 Maple Ridge controller features a PCIe 3.0 x4 cable and supports dual Thunderbolt 4 interfaces with dual DP 1.4a inputs.


Intel’s official Thunderbolt 4 certification requirements include.
Support for simultaneous output of two 4K displays or connection of an 8K display
Support for 32Gb/s PCIe transfer rate
Support for Intel’s VT-d based DMA protection
Certification requires minimum support for 40Gbps speeds over 2 meters of common cable
Docking stations supporting a minimum of 4 Thunderbolt interfaces
At least one interface supports 100W charging
Wake up the computer from sleep with a touch of the keyboard or mouse when the Thunderbolt docking station is connected
