Other Parts Discussed in Thread: TS3DV642

Hi,

 

My customer wants the following information.

Could you please tell us the following question.

 

1.Can it support a signal of 4k2k30p (3Gbps)?

2. Did you measure the eye pattern at signal of 4k2k60p(3Gbps)?

3. Did you measure the max dissipation power at signal of 4k2k60p(3Gbps)?

 

Regards,

Kanemaru

    Hello Kanemaru-san,

    1.  Yes

    2.  4k2k60p is not possible with HDMI 1.4.  But we did measure the 3.4 Gbps eye for 4k2k30p.

    3.  As this is a passive switch,  the signal speed through the device has no impact on our devices power consumption (ICC).  If you are asking about the power dissipated through the switches of the device because of the current running through the switches then no we did not.

    Hi, Andrew

    Thank you for your prompt reply.

    Could you please send us ”the 3.4 Gbps eye pattern for 4k2k30p".

    Hi, Andrew

     

    the "device" is the HDMI sink device(Display port connector etc…)?

    Could you please tell us the difference "with device" and "no device".

    And, could you please tell us the measurement environment of the eye pattern.

     

    [my guess]

    <with device>

    Signal generator -> TS3DV642 [B port] -> HDMI sink device(Display port connector etc…)

                                                                                (Measuring instrument (eye pattern))

     

    <No device>

    Signal generator -> TS3DV642[B port] -> PCB through path(No device)

                                                                                (Measuring instrument (eye pattern))

    Hello Kanemaru-san,

    Here's the setups:

    1. With Device

    Signal Generator -> TS3DV642 -> High Speed Scope with HDMI terminations

    2. Without Device

    Signal Generator -> Through path of high speed board -> High Speed Scope with HDMI terminations

    As you can see the diagram are very similar, showing how little the TS3DV642 impacts the signal passing through.

    Andrew
