TX7332: Dual TX7332 on a board not pulsing.

Philippe Rubbers

Part Number: TX7332

When connecting two TX7332 to a single AFE, what state must the second TX7332 be in?
Our board design works find with one TX7332 installed, but as soon as we solder in the 2nd TX7332, no pulse is measured on the output pins (of the 1st TX7332).
I assume it is a setting on the 2nd TX7332 which is at fault.
If it was still pulsing, but not visible on the AFE, I would suspect the TR Switch, but no pulse at all does not make sense to me.
Please can you assist.

Hi,

We need to see what all signals are shared between the two Tx devices. Can you share schematic? In case if you dont want to share it in public domain then you can send it to support_us_afe_tx@list.ti.com id and we can discuss further there.

Thanks!
