Describe：
JHL8540, code-named Maple Ridge, is the first standalone Thunderbolt™ 4 controller chip launched by Intel. It enables non-Intel platforms (such as AMD) to support Thunderbolt 4 functionality.
This chip connects to the host via a PCIe 3.0 x4 channel, and requires the full bandwidth to be certified. It provides 2 Thunderbolt 4 interfaces (in USB-C form) externally, supporting a maximum data transfer rate of 40Gbps, is compatible with USB4 and DisplayPort 1.4a protocols, supports dual 4K or single 8K video output, and has a maximum power supply capacity of 100W.
Features ：
• Independent control: The main control chip for devices such as PCs and tablets, enabling non-Intel platforms to support Thunderbolt 4.
• High-speed interface: Supports PCIe 3.0 x4 connection with the host, providing two 40Gbps Thunderbolt 4 interfaces externally.
• Video and power supply: Supports dual DisplayPort 1.4a inputs, with a maximum power supply of 100W.
• Wide compatibility: Compatible with USB4, USB 3.1, and DisplayPort protocols, and backward compatible.
• Packaging and specifications: The packaging area is approximately 10.7 x 10.7mm. The step version is B0, and the specification code SRH4R is the order identification code.
Application：
• High-end motherboards: Provide native Thunderbolt 4 interfaces for desktop and workstation motherboards, commonly found in Intel 500/600/700 series and specific AMD platform motherboards.
• Expansion cards: Such as ASUS ThunderboltEX 4 and MSI ThunderboltM4 8K, PCIe expansion cards, used to add interfaces to motherboards that do not support Thunderbolt 4.
• Laptops and tablets: As independent control chips, provide high-speed expansion and connection capabilities for devices.
