PTN38007 Multi-protocol USB4 20 Gbps linear redriver Rev. 2.1 8 December 2021 Product data sheet 1 General description PTN38007 is a high-performance USB Type-C USB3.2/DisplayPort/Thunderbolt3/USB4 multi-protocol linear redriver that is optimized for USB3.2, DisplayPort 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 2 pin strapping or I C 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.NXP Semiconductors PTN38007 Multi-protocol USB4 20 Gbps linear redriver 2 Features and benefits Flexible multi-protocol linear redriver supports five signaling combinations specified in USB Type-C and VESA specifications Mode 0: Deep Power saving Mode 1: USB3.2 Gen1x1/Gen1x2/Gen2x1/Gen2x2 Mode 2: USB3.2 + DP 2-Lane + AUX snooping Mode 3: DP 4-Lane + AUX snooping Mode 4: Thunderbolt3 mode + SB snooping Mode 5: USB4 mode + SB snooping Supports USB 3.2 Gen1x1, Gen 1x2, Gen2x1, Gen2x2 (5 Gbps and 10 Gbps) 2 I C register based Flat gain control Peaking gain of +12.1 dB at 5 GHz Output swing linearity control: 500 mVppd to 950 mVppd Support DP2.0 link rates at 1.62 Gbps (RBR), 2.7 Gbps (HBR), 5.4 Gbps (HBR2), 8.1 Gbps (HBR3),10 Gbps (UHBR10), 13.5 Gbps (UHBR13.5), 20 Gbps (UHBR20) DP AUX monitoring during DP link training to control DP channel 2 I C register based Flat gain control Peaking gain of +10.2 dB at 4.05 GHz, 20 dB at 10 GHz Output swing linearity control: 500 mVppd to 950 mVppd Support Thunderbolt3/USB4 lane speed of 10/10.3125/20/20.6 Gbps SBTX and SBRX snooping 2 I C register based Flat gain control Peaking gain of +20 dB at 10 GHz Output swing linearity control: 500 mVppd to 950 mVppd Compliant to DisplayPort, Thunderbolt3 and USB4, USB3.2 standard and USB Type-C Alternate mode interoperability testing Implements USB Type-C Safe state conditions on all connector facing pins 2 Configurable via I C interface with a configurable address pin Integrated termination resistors provide impedance matching on both transmit and receive sides Autonomous Orientation detection of USB-C connection and its configurable enable control Supports maximum voltage limit (V ) to align to the latest USB3 specification voltage jump and computing platform capabilities RX equalizers on all high-speed inputs to compensate for signal attenuation Automatic receiver termination detection in USB 3.2 and USB4 modes Good linearity over the frequency band (50 MHz to 10.3 GHz) and voltage dynamic range Excellent Differential return loss performance: < -16 dB up to 10.3 GHz Flow-through pin-out to ease PCB layout and minimize crosstalk effects Very low crosstalk: DDNEXT < -50 dB up to 10.3 GHz PTN38007 All information provided in this document is subject to legal disclaimers.
