Other Parts Discussed in Thread: SD3GDAEVK, LMH0344


I got the below question:

We bought the SD3GDAEVK SDI reclocker EVB, when we tried to evaluate it we encounter the following issues :

  1. In general the EVB does not work
  2. After some debugging we found the following :
    1. No output signal from the Equalizer
    2. No 27Mhz clock signal

 We would like to evaluate this device and were hoping to get it done by now, unfortunately due to the malfunction EVB we didn’t yet manage to do any progress.

Can you please try to replace this EVB? In the mean time do you have the reclocker IC or similar EVB that we can test in house to complete our urgent task.


  • Greetings,

    I apologize for the bad experience you are having with this board. 

    Please note the link to this board schematic:

    Please check to make sure the jumpers are set properly. You can use a short cable and use your scope probe to monitor the signal all the way from the BNC to the output of the LMH0344. Please make sure the Mute strap is set properly(J2). Worst case, please talk to your local TI sales to see if they can replace this board. These boards get tested and thus we should not have this problem.
