PI3HDX6311

Description

The PI3HDX6311 is a 4-differential channel ReDriver™ that supports multiple data rates. This device offers programmable equalization, output swing, and flat gain through pin strapping. With its ability to reduce inter-symbol interference, the PI3HDX6311 optimizes performance over a range of physical mediums.

For HDMI1.4 application, the ReDriver is configured as a limited ReDriver, where the ReDriver differential output swing is defined by the ReDriver swing set ting, to ensure the HDMI compliant levels at the receptacle . For HDMI2.0, the ReDriver is configured as a linear ReDriver, where the ReDriver differential output swing is directly proportional to the received signal, to ensure the ReDriver is function as a trace canceller. The linear ReDriver mode is also inherently transparent to link training signals.

The PI3HDX6311 is transparent to link training signals, and its input and output signals can be AC or DC-coupled or mixed, eliminating the need for additional level shifter components for data channels. The integrated equalization circuitry provides signal integrity flexibility before the ReDriver, while the integrated linear amplifier/buffer circuitry offers flexibility after the ReDriver. This device can also support HDMI2.0 compliant output signals for dual-mode DisplayPort level shift applications.
