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), the device gets into GPIO mode or I2C 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 level of configurability, PTN36502/PTN36502A can operate in I2C 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 sign...
