Pericom Semiconductor’s PI3DPX1203 is DisplayPort
compliant, 8Gbps link speed, single differential channel
Linear ReDriver with Link Training transparent mode.
Since DisplayPort source and sink-side device are
unaware of the Linear ReDriver, they never generate
AUX link training transactions, and pass through all the
AUX transactions between source and sink-side devices.
PI3DPX1203 provides programmable input equalization,
linear swing and flat gain control to optimize output
over a variety of physical mediums by reducing intersymbol
interference. The integrated linear equalization circuitry
provides flexibility with signal integrity of the signal before
and after the ReDriver. A low-level input signal detection
and output squelch function is provided.


  • PCs and Peripherals
  • DisplayPort Active cables


  • DisplayPort standard 1.3 Compliant Linear ReDriver
  • Support flexible placement for Active cable, Sink
    and Source side
  • Ideal for USB Type-CTM sink and source-side app-
    lication with PD controllers
  • Transparent DisplayPort link training. No need Aux
    Link training listener circuits
  • Low latency transparent for the DisplayPort link
    training allow for Sink-side application
  • Linear input equalization increases link margin
    for systems implementing Decision Feedback
    Routing Equalizers (DFE)
  • Independent channel configuration of input
    equalization, output swing and flat gain
  • Pin strap or I2C programmable for device
    configuration setting
  • Channel order swap and polarity swap support
    Aux channel connect directly from source to sink
  • 4-bit selectable address bit for I2C port
  • Supply Voltage: 3.3V
  • Package : 42-pin TQFN (3.5mm x 9mm)
