Hi

 

My customer using ADM2587E.

The ADM2587E a customer designed is estimated, evaluation  board is the same result.

But , other communication device is 5V supplyed.

 

My custmer setting is

Cable : two meter

Data rate : 57.6K - 115.2Kbps

 

1, In case No RT ,Not connect GND

Output has 4.5us delay

 

2, Connet RT or Connect GND

Output has not delay

 

Question :

・Table 3 has timing chart at connected RT ,Does a short distance need a RT certainly?

 

・What is the delayed cause of this 4.5us? No RT? Not Connected GND? or 5V supplyed?

 

 

Best regards

HOD
