6Gbps 4-Channel HDMI 2.0 Linear ReDriver/Dual Mode DisplayPort Level-Shifter


Diodes’ PI3HDX1204D is a multi-data rate, 4-differential channel ReDriver™. The device provides programmable linear equalization, output swing and flat gain, by either pin strapping
option or I2C Control, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference.

The PI3HDX1204D supports four 100Ω Differential CML data I/O’s and extends the signals across distant data pathways on the user’s platform. The integrated equalization circuitry provides flexibility with signal integrity of the signal before the ReDriver, whereas the integrated linear amplifier/buffer circuitry provides flexibility with signal integrity of the signal after the ReDriver.
