PI3HDX12221

12Gbps 4-Channel HDMI2.1 2-to-1 Active Mux with Linear ReDriver

Description

The PI3HDX12221 is a 2-to-1 active mux switch for 4-channel HDMI link with data rate up to 12Gbps for HDMI2.1 standard. It provides the maximum equalizer gain controls up to +11dB (HDMI2.1 @ 6GHz) and +7dB (HDMI2.0 @ 3GHz) to compensate the insertion loss along the channel connection.

The non-blocking linear RedriverTM design ensures the differential signals conveying pre-shoot and de-emphasis equalization waveforms to be transparently transmitted from source side to the receiver side and linearly compensate the channel loss to achieve longer channel extension. 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 output linearity adjustments support the eye diagram opening adjustment.

With the combinational logic control design, the device has reduced the control pins to achieve more compact package dimension. Users can use pin strap method to select different EQ gains, flat gains and output swing linearity for flexible design tuning.
