The PI3HDX1204B1 is a ReDriver™ device suitable for HDMI 2.0 6.0 Gbps with programmable high equalization, output swing and de-emphasis control mode. The maximum EQ of the device is +22dB @ 6Gbps and it can deliver 2x better additive jitter performance compared to the traditional ReDriver devices. In addition, the device can support the Dual-Mode DisplayPort Level Shifter application for HDMI 2.0 compliant output signals. The device's EQ/SW/De-emphasis settings can be configured by the pin-strapping or the I2 C programming to optimize differential signal performance over various physical media.


  • HDMI 2.0 compliant Limiting-type ReDriver to compensate high insertion loss of the long TMDS signal transmission
  • Supports Dual-mode DP HBR3 to HDMI 2.0 Level Shifting
  • Double the jitter performance than conventional CMOS-process ReDriver
  • Input EQ supports 16 steps up to +22.2dB @ 3GHz (6Gbps),
  • 4 steps De-emphasis and 4 steps output voltage swing setting
  • Independent each channel configuration for Equalization, Output Swing and De-emphasis
