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 Re-
Driver 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.
