6Gbps 4-Channel HDMI2.0 Linear redriver with Low EQ option//Dual Mode DisplayPort Level-Shifter


Diodes’ PI3HDX1204C is a multi-data rate, 4 differential channels 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. PI3HDX1204C supports four 100Ω Differential CML data I/O’s and extends the signals across other 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. The IC (chip) provides low equalizer options for short prechannel.
The device can support dual-mode DisplayPort level shift application for HDMI2.0 compliant output signals.
