W-QFN3060-40.png3.3V 13.5Gbps DP2.1 1-to-2 Active DeMux with Linear Redriver
The PI3DPX8112 is a 1-to-2 active mux linear ReDriver™ for 4-lane DisplayPort™ link with data rate support up to 13.5Gbps for DP2.0 (UHBR13.5, UHBR10), DP1.4 (HBR3), DP1.2 (HBR2), DP1.1 (HBR1) and DP1.0 (RBR) standards. The maximum equalizer gain controls are +15dB (DP2.0@6.75GHz) and +8.5dB (DP1.4@4.05GHz) to compensate for insertion loss along the channel connection.
The non-blocking linear ReDriver design ensures that the differential signals conveying pre-shoot and de-emphasis equalization waveforms be transmitted from source-side to receiver-side with DFE. It helps to optimize the overall channel link adjustment conducted by the system transmitter and receiver. The CTLE equalizers are implemented at the inputs of the ReDriver to reduce the ISI jitters and compensate for channel loss. The programmable flat gain and linearity adjustments support the eye diagram opening. With the combinational logic control design, users can use a
pin strap method to select different EQ gains, flat gains, and output swing linearity for flexible design tuning.
