Type-C USB 3.1 Gen 1 and DisplayPort V1.2 Combo Redriver
- 本页面包含有关样品阶段产品的信息。此处的规格和信息如有更改，恕不另行通知。如需了解其他信息，请联系支持人员或您的销售代表。
PTN36502 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 flow to extend the signal reach.
PTN36502 addresses high-speed signal quality enhancement requirements for implementation of a USB Type-C interface on a platform that supports the VESA DisplayPort Alt Mode Standard v1.0a, which includes a DisplayPort Branch or Sink function.
PTN36502 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/de-activate internal circuitry and logic.
PTN36502 is powered by a 1.8 V supply and it is available in a small thin HX2QFN24 package with 2.4 mm x 3.2 mm x 0.35 mm and 0.4 mm pitch.

Features
Key Features
- Flexible Type-C USB/DP combo re-driver supports four signaling combinations specified in USB Type-C and VESA DisplayPort Alt mode standards through either I²C target interface or ternary GPIO pins
- 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: SuperSpeed USB 3.1 Gen 1 standard, DisplayPort v1.2 standard for DFP applications and 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)
- 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
- Excellent Differential and Common return loss performance
- Hot Plug capable
- ESD HBM 8 kV CDM 1 kV on high-speed pins and HBM 4 kV CDM 500 V on control pins
- Supports IEC61000-4-5 8/20 us ±16 V Surge test performance with external 4.7 Ω series resistors on the DRX1P/N, DRX2P/N and DAUXP/N pins
- Operating temperature range -40 to +85 °C
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
