TS3DV642: HDMI 1.4 & HDMI2.0 impedance test method.

Part Number: TS3DV642

hi,

    I am using TS3DV642 in HDMI has test impedance issue.

    In the same channel, at add TS3DV642 in my circuit, HDMI 2.0 impedance test is fail but  HDMI 1.4 test is pass.

    how to test impedance at HDMI 1.4 & HDMI 2.0?

    What is the test standard for HDMI1.4 & 2.0?

thanks.

  • Hi Wu,

    The results for HDMI 1.4B and HDMI 2.0 sink TDR are the same, but the acceptable termination impedance is lower for HDMI 2.0. To properly test with the TS3DV642, the sink should be powered on (Sink_Diff_PowerOn = Y) and the mux needs to be enabled (not in powerdown mode).

    Hi Jmmn,
    In HDMI 2.0 test, TS3DV642 is power on and mux enabled, but the test also fail.
    Btw, is TS3DV642 through pass the HDMI 2.0 impedance test?

    thanks.
