Diodes Incorporated PI3HDX12311 & PI3HDX6311 Hybrid ReDrivers™

Diodes Inc. PI3HDX12311 and PI3HDX6311 Hybrid ReDrivers™ are both 3.3V quad-channel hybrid ReDrivers. The PI3HDX12311 supports HDMI 2.1 fixed rate link (FRL) up to 12Gbps and transition minimized differential signaling (TMDS) up to 6Gbps; the PI3HDX6311 supports HDMI 2.0 TMDS up to 6Gbps. Both are backward compatible with HDMI 1.4. For HDMI 1.4 applications, both are configured as a limited ReDriver (where the swing setting defines the ReDriver's differential output swing), ensuring HDMI-compliant levels at the receptacle. For HDMI 2.0 and HDMI 2.1, the devices are configured as linear ReDrivers (where the differential output swing is directly proportional to the received signal), which ensure the ReDrivers function as trace cancellers. The linear ReDriver mode is also inherently transparent when linking training signals.

The Diodes Inc. PI3HDX12311 and PI3HDX6311 have pin strap mode control for operational mode, equalization, flat gain, output swing (SW), and output -1dB linearity swing (N1SW). Both devices support dual-mode DisplayPort (DP++) level shift applications for HDMI TMDS output signals. The device's input and output signals can be AC or DC-coupled or mixed, eliminating the need for additional level shifter components from the data channels. The PI3HDX12311 and PI3HDX6311 are available in the tiny X1-QFN2845-32 (XEA32) package occupying only 2.85mm x 4.5mm PCB area and operate across the -40ºC to +70ºC temperature range.
