PRODUCTION DATA.
HDMI2.0[3] standard requires the transmitter termination impedance should be between 75 to 150-Ω. Older versions of the HDMI standard required no source termination. For HDMI1.4b[2] when data rate over 2 Gbps, the output performance could be better if the termination value between 150 to 300-Ω which was allowed. The SNx5DP159 supports three different source termination impedances for HDMI1.4b[2] and HDMI2.0[3]. Pin 36, TX_TERM_CTL, offers a selection option to choose the output termination impedance value. This can be adjusted by I2C[4]; reg0Bh[4:3] TX_TERM_CTL.
