PTN36502/PTN36502A Type-C USB 3.1 Gen 1 and DisplayPort v1.2 combo redriver Rev. 3 28 September 2018 Product data sheet 1 General description PTN36502/PTN36502A is a Type-C USB 3.1 Gen 1/ DP1.2 combo redriver that is optimized for USB 3.1 Gen 1 and DisplayPort applications on either the Downstream Facing Port (DFP) or Upstream Facing Port (UFP) by following the four high-speed differential data flows to extend the signal reach. PTN36502/PTN36502A addresses high-speed signal quality enhancement requirements for implementation of a USB Type-C interface in a platform that supports the VESA DisplayPort Alt Mode Standard v1.0a, includes a DisplayPort Branch or Sink function. PTN36502/PTN36502A has three ternary (3-level) configuration pins (SCL/C1, SDA/ C2 and EN), and depending on the state of EN pin during Power-On Reset (POR), 2 the device gets into GPIO mode or I C mode. When EN is driven LOW during POR, PTN36502/PTN36502A operates under GPIO mode, and these three ternary pins are used to configure DFP/UFP configuration followed by mode setting (USB 3.1 Gen 1 and DisplayPort TX and RX function selection), as well as selecting receive equalization, transmit de-emphasis and output swing level. To support applications that require greater 2 level of configurability, PTN36502/PTN36502A can operate in I C mode when EN pin is left open (OPEN/NC) during POR. For DisplayPort (DP) operation, PTN36502/PTN36502A has a built-in internal crossbar function that can swap AUXP and AUXN signals for supporting plug orientation. PTN36502/PTN36502A monitors the AUX transactions and adjusts the DisplayPort transmitters output swing and emphasis setting during DP Link training accordingly. PTN36502/PTN36502A has built-in advanced power management capability that enables significant power saving under USB 3.1 Gen 1 Low power modes (U2/U3). It can detect LFPS signaling and link electrical conditions and can dynamically activate/deactivate internal circuitry and logic. The device performs these actions without host software intervention and conserves power. The host processor keeps PTN36502/PTN36502A in deep power saving or USB operation mode until DP Alt mode is entered. PTN36502/PTN36502A is powered from a 1.8 V supply and it is available in an extremely thin HX2QFN24 package with 2.4 mm x 3.2 mm x 0.35 mm and 0.4 mm pitch.NXP Semiconductors PTN36502/PTN36502A Type-C USB 3.1 Gen 1 and DisplayPort v1.2 combo redriver 2 Features and benefits Flexible Type-C USB/DP combo redriver supports four signaling combinations specified 2 in USB Type-C and VESA DisplayPort Alt Mode Standards through either I C slave interface or ternary GPIO pins Mode 1: One USB 3.1 Gen 1 port only Mode 2: One USB 3.1 Gen 1 port + 2 lane DP + AUX channel Mode 3: 4 lane DP + AUX channel Supports USB 3.1 Gen 1 data rate of 5 Gbps, and DisplayPort data rates at 1.62 Gbps, 2.7 Gbps and 5.4 Gbps (HBR2), AUX at 1 Mbps Compliant to SuperSpeed USB 3.1 Gen 1 standard Compliant to DisplayPort v1.2 standard for DFP applications Compliant to VESA DisplayPort Alt mode on USB Type-C standard Implements USB Type-C Safe state conditions on all connector facing pins 2 Configurable via ternary GPIO or I C interface (operating up to 1 MHz) 2 PTN36502 7-bit I C address = 001 1010 2 PTN36502A 7-bit I C address = 001 0010 Integrated termination resistors provide impedance matching on both transmit and receive sides RX equalizers on all inputs to compensate for high speed signal attenuation in PCB and cable channels Active TX De-emphasis and Output swing on all outputs to assure high frequency boost Automatic Receiver Termination Detection in USB 3.1 Gen 1 mode Supports auto power saving modes during USB 3.1 Gen 1 operation DP AUX sideband crossbar switch for Type-C plug orientation DP AUX monitoring during DP link training to control DP TX output driver adjustment Flow-through pinout to ease PCB layout and minimize crosstalk effects Low crosstalk: DDNEXT < -45 dB at 2.7 GHz Low active current consumption USB 3.1 Gen 1 only (Mode 1) active power: 115 mA (typ) for VOS = 1Vpp and DE=-3.5 dB 2-lane DP HBR2 level 0 (Mode 3): 75 mA (Level 0 : 400 mV with no Pre-emphasis) 1-lane DP HBR2 level 0 (Mode 3): 38 mA (Level 0 : 400 mV with no Pre-emphasis) 4-lane DP only HBR2 level 0 (Mode 3): 150 mA Power-saving states: USB 3.1 Gen 1 mode (mode 1): 1.16 mA (typ) when in USB 3.1 Gen 1 U2/U3 states 0.77 mA (typ) when no connection detected (USB Rx detection enabled) (when a USB Type-C to USB Type-A adapter is connected to a USB Type-C port, but no USB Type-A device is attached to the adapter) DP sleep D3 mode (Mode 2/3): 0.5 mA (typ) 3 A (typ) when in deep power-saving state Excellent Differential and Common return loss performance Hot Plug capable Single Power Supply 1.8 V Extremely thin HX2QFN24 package 2.4 mm x 3.2 mm x 0.35 mm with 0.4 mm pitch PTN36502 PTN36502A All information provided in this document is subject to legal disclaimers.
