Type-C USB/DP Combo Redriver

NXP's PTN36502 is a combo signal redriver that enhances USB 3.1 Gen 1 and 4-lane DP 1.2 (HRB2) signal integrity. PTN36502 is packaged in an ultra-small QFN package 2.4 mm x 3.2 mm. The small form factor is ideal for mobile computing, smartphones, tablets, and any small form factor applications.

The PTN36502 IC improves signal integrity on a host system. It integrates DP AUX snooping function and AUX crossbar switch, and it offers ultra-low standby power consumption of 1.8 mW (U2 mode). The IC can operate with 1.8 V VDD, which is a common voltage rail across mobile platforms/systems.

Features
  • Wide supply voltage works with host processor that integrates DP/USB crossbar switch
  • USB3.0 (USB3.1 Gen 1) and 4-lane DP1.2 (HBR2) operation
  • Supports DP AUX snoop function for automatic link rate and lane count detection and DP transmit signal swing adjustment
  • Integrated AUX crossbar switch with USB-C safe state support
    • Standby power (U2/U3 mode): 2 mW
  • Low power design with very low power saving modes
    • Active power: 190 mW @ 1.8 V
  • Support both I2C and GPIO control modes for programmability
    • USB and DisplayPort Rx EQ, Tx emphasis and amplitude setting
Applications
  • USB Type-C™ host/source
    • Smartphones and tablets
    • Notebooks, AIO, and desktop computers
    • Hub or dock devices
  • USB Type-C device/sink
    • Docking stations
    • Display units
