Multi-Protocol USB4 20 Gbps Linear Redriver Rev PTN38007 Multi-protocol USB4 20 Gbps linear redriver Rev. 1.0 — 7 June 2021 Product data sheet 1 General description PTN38007 is a high-performance USB Type-C USB3.2/ DP1.4/Thunderbolt3/USB4 multi- protocol linear redriver that is optimized for USB3.2, DisplayPort 1.4 and Thunderbolt3/ USB4 applications on either the downstream facing port (DFP) or upstream facing port (UFP) application. PTN38007 addresses high-speed signal quality enhancement requirements for implementation of USB Type-C interface in a platform that supports the USB Type- C, VESA DisplayPort and Thunderbolt Alternate Mode Standards. This device also implements the snooping monitor of the sideband (SB) signals from DP mode (AUX) and Thunderbolt3/USB4 mode (SBTX/RX) to optimize the configuration, power saving mode and performance. The device provides programmable linear equalization, output swing linearity control by pin strapping or I2C control to improve signal integrity and enable channel extension by reducing inter-symbol interference (ISI). DisplayPort AUX snooping is performed to follow certain DisplayPort source-sink AUX transactions and configure the redriver to meet link requirements. Thunderbolt3/USB4 SB snooping is performed to optimized the power saving mode and configuration. For USB operation, PTN38007 has built-in advanced power management capability that enables significant power saving under USB3.2 low power modes (U2/U3). It detects LFPS (Low Frequency Periodic Signaling)/LBPM (LFPS Based PWM Message) signaling to configure the operation (USB3.2 Gen 1/Gen 2 & x1/x2) and link electrical conditions and it activates/deactivates internal circuitry and logic dynamically. The device performs these actions without host software intervention and conserves power. The host processor keeps PTN38007 in deep power saving or USB mode until alternate mode has been entered. The device is tailored to support USB3.2 and USB4 electrical idle, receiver detection and power saving modes. It maintains two separate input signal detectors – loss of high- speed signal (LOS) and USB LFPS detectors with built-in hysteresis. For DisplayPort (DP) operation, PTN38007 monitors the AUX transactions and adjusts the DisplayPort channel setting during DP Link initialization and training. For Thunderbolt3 (TBT3) and USB4, PTN38007 monitors SBTX and SBRX sideband traffic to optimize the performance. It decodes LT transaction to determine link and power status. PTN38007 is powered from a 1.8 V supply. It is available in a small high performance HWFLGA36 package.

  • USB-IF Announces Publication of USB4™ Specification Specification Now Available for Download on USB-IF Website; Doubles Bandwidth to Extend USB Type-C® Performance
    DEVELOPER UPDATE CONTACT: Joe Balich USB-IF PR +1 503-619-4113 [email protected] USB-IF Announces Publication of USB4™ Specification Specification now available for download on USB-IF website; doubles bandwidth to extend USB Type-C® performance Beaverton, OR, USA – September 3, 2019 – USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced the publication of the USB4™ specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. The USB4 architecture is based on the Thunderbolt™ protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols. The development of the USB4 specification was first announced in March 2019 by the USB Promoter Group. It is now officially published by USB-IF and available for download at www.usb.org. Key characteristics of the USB4 solution include: • Two-lane operation using existing USB Type-C® cables and up to 40Gbps operation over 40Gbps certified cables • Multiple data and display protocols that efficiently share the maximum aggregate bandwidth • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3 As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected.

General Information Introduction Eliminate the confusion surrounding the Type-C connector with a dock that adapts to the interface it is connected to. Thunderbolt 3 and USB-C share the same connector, and up until now Thunderbolt 3 devices have only worked on Thunderbolt 3 host laptops, creating confusion for many users. The USB-C HDMI Dock breaks this mould by utilizing the latest Thunderbolt technology to adapt itself to your laptop. It is essentially a full Thunderbolt 3 (40Gb/s) device that has the latest Thunderbolt advancements in order to be compatible with non-Thunderbolt 3 laptops that feature USB-C. In addition, the USB-C HDMI Dock is also compatible with Thunderbolt 4 computers. Now everyone can benefit from a feature rich dock without compromising on connectivity and compatibility. 3 General Use Warnings • Please read the USB-C HDMI Dock manual thoroughly and familiarize yourself with the product before use. • Avoid using the USB-C HDMI Dock in extremely hot and cold environments.
