3.3 TMDS1204 DC Gain Adjustment

The TMDS1204 equalizer is used to clean up inter-symbol interference (ISI) jitter or loss from the bandwidth-limited board traces or cables. The TMDS1204 provides three sets of CTLE curves with each curve having 16 AC gain settings and 3 DC gain settings. For the DC gain, the TMDS1204 provides a globally lane control feature through the DCGAIN pin in pin strapping mode.
