Description

The PI3DPX8121 is a 2-to-1 active mux switch for 4-lane Display- Port link with data rate support up to 10Gbps for DP1.4 and the new DP2.0 standards. The maximum equalizer gain controls are +10dB (DP2.0@5GHz) and +8.5dB (DP1.4@4.05GHz) to compensate the insertion loss along the channel connection.

The Link Training tunable linear RedriverTM design supports the LTTPR (Link Training Transparent PHY Repeater) redriver data
path type. It ensures the differential signals conveying pre-shoot and de-emphasis equalization waveforms to be transmitted from source side to the receiver side 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 various EQ gains, flat gains and output swing linearity for flexible design tuning.
