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.

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)

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
2.4 mm x 3.2 mm x 0.35 mm with 0.4 mm pitch
