3 OM584. Introduction PTN604 is a very small, low power differential channel to active demultiplexer with integrated SuperSpeed USB.0 redriver IC that can switch two differential signals to one of two locations. The active demux has optimized performance with minimized crosstalk, as required by the high-speed serial interface for type C connector. PTN604 allows expansion of existing high speed ports for very low power consumption. PTN550A is a small thin low power CC Logic chip supporting the USB Type-C connector application with Configuration Channel (CC) control logic detection and indication functions. The features of PTN550A enable USB Type-C connector to be used in both host and device ends of the Type-C cable. It can support Type-C to USB legacy cables and adapters defined in USB Type-C Spec. PTN550A can work autonomously, or can connect to a controller through IC-bus interface. This document describes the user s manual of PTN604 USB Type-C SuperSpeed Active Demux, and also PTN550A CC logic chip for orientation detection on the USB Type-C cables, including Overall PCB connectors, jumpers, and power supplies Equipment/Tools that this board will be interfacing with for board testing System level connections such as cables and connectors that this board will be plugged into. Purposes For engineers to evaluate the performance of PTN604, including verifying system level features/performances/functionalities such as o Signal integrity measurements such as jitter and eye diagrams o Verify power management schemes in U0/U/U/U states o Power consumption measurement during U0/U/U/U states. o Allow access to settings such as receiver equalizer and transmitter output swing level and de-emphasis for the channel facing the application processor side, or for the channel USB Type-C connector side. For engineers to evaluate the performance of PTN550A, including verifying system level features/performances/functionalities such as o CC logic (CC/CC) orientation detection Tel: (408)-58-55,

General Description. Layout of PTN604 and PTN550A This application board is designed to evaluate PTN604 and PTN550A specifically. Socket footprints are no longer available on the evaluation board, and only IC footprints are provided for direct soldering purpose. There are two possible configurations to use this application board. Host (DFP) Mode connect to a host PC via a standard A-A cable (cables are not provided), and connect to a device via a USB-Type-C to Type-A receptacle.. Device (UFP) Mode connect to a host PC (such as Macbook or Chromebook) via a standard type-c cable, and connect to a device (such as thumb drive) via on-board Type- A receptacle. PTN550A has special EXT_ feature that can be used to select which path to enable on PTN604, based on the type-c cable s orientation. Note that PTN550A does not have this feature, and thus won t be easy to demonstrate the selection function. If customers would like to evaluation PTN550, please make a special request to marketing, and we can provide the correct part number for evaluation. Tel: (408)-58-55, 4

Board Power This demo board can be powered from three different power sources: o o o USB Type-A (DFP mode, from a Type-A host) USB Type-C (UFP mode, from a Type-C host) DC Barrel (5V) Three different power paths are diode-ored together through D7/D8/D9 to provide power input to.v and.8v LDOs. A momentary toggle switch (S) is used to disconnect power inputs to LDOs while pressing down. By default, the momentary toggle switch is in the ON position. 4. Power Measurement Customers can use J5 for PTN604 power measurement, and J9 for PTN550A power measurement. Note that PTN550A s VDD can be up to 5.5V, and IO voltage Tel: (408)-58-55, 0

11 OM584 can be varied by changing J setting. For normal operation, jumpers should be installed on J5 and J. 4. PTN604 Channel Settings PTN604 channel settings can be adjusted through J (CHSETx) and J (CHSETx). CHSETx is used to set channel condition on the USB Type-A side, and CHSETx is used to set channel condition on the USB Type-C side.

12 OM PTN550A I C Mode By default, PTN550A operates in non-i C mode, and OUT/OUT/OUT pins are configured as outputs. In order to place PTN550A in I C mode, customers should configure pin 5 (ADR/) with either a pull up resistor or a pull down resistor during power up, and OUT/OUT/OUT are re-configured as I C_SDA/ I C_SCL/INTB functions. Note that when operating in I C mode, output function is disabled by default. However, is used by on-board discrete logic to enable/disable 5V power source and sink load switches, as well as VBus discharge circuit on the Type- C connector side. In order for these control circuits to operate correctly, customers should always write 0x00 to PTN550A s internal address 0x09 to enable output. 5. Different Operation Modes PTN550A/PTN604 application board can be configured to operate in either one of the following configurations. Host (DFP) Mode connect to a host PC via a standard A-A cable (cables are not provided), and connect to a device via a USB-Type-C to Type-A adapter. In this mode, the demo board can be powered by the USB host, and 5V source load switch (U) is enabled to pass VBus power from Type-A side to Type-C side. Device (UFP) Mode connect to a host PC (such as Macbook or Chromebook) via a standard type-c cable, and connect to a device (such as thumb drive) via on-board Type-A receptacle. In this mode, the demo board can be powered by the USB Type-C host, and 5V sink load switch (U5) is enabled to pass VBus power from Type-C side to Type-A side. Tel: (408)-58-55,

Conclusion Using PTN550A/PTN604 application board, customer can validate most of the functions on both USB redriver for type-c application, and also CC logic chip for orientation detection. On board load-switches can be enabled/disabled based on the detecting status of PTN550A through simple discrete logic without any firmware control. Tel: (408)-58-55,
