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 signals for supporting plug orientation.

PTN36502/PTN36502A monitors the AUX transactions and adjusts the DisplayPort

transmitter’s 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.

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

in USB Type-C and VESA DisplayPort Alt Mode Standards through either I2C 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

• Configurable via ternary GPIO or I2C interface (operating up to 1 MHz)

• PTN36502 7-bit I2C address = 001 1010

• PTN36502A 7-bit I2C 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 μA (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
