The PI3HDX12212 is a 1-to-2 Active DeMux linear ReDriver for 4-lane HDMI link with data rate support up to 12.0Gbps for HDMI2.1 (12Gbps), HDMI2.0 (6Gbps), HDMI1.4 (3.4Gbps), HDMI1.2 (2.5Gbps) standards. The maximum equalizer gain controls are +14dB (HDMI2.1@6GHz) and +8.5dB (HDMI2.0@3GHz) to compensate the 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 channel loss. The programmable flat gain and linearity adjustments support the eye diagram opening. With the combinational logic control design, users can use pin strap method to select different EQ gains, flat gains, and output swing linearity for flexible design tuning.
