Tool/software:
Hello team,
At datasheet of THVD1520, we can see below comment
"To eliminate line reflections, each cable end is terminated with a termination resistor, RT, whose value matches the characteristic impedance, Z0 , of the cable. This method, known as parallel termination, allows for higher data rates over longer cable length."
- Customer status
1. They use a total of 32 modules.
2. The distance from the first node to the last node is about below 1 meter.
3. The customer have to use same PCB for all nodes. They don't know which module will be the first or last module.
Q1 If the customer have to use same PCB for 32 node, Should we add a termination resistor to all nodes, or should we delete a termination resistor? which one is better?
Q2 If we should add a termination resister to all 32 node, How can we fix the value?
Please let me know your opinion.
Thank you.
