DS320PR410: Properly disable channels on DS320PR410

Part Number: DS320PR410

Hello, I am developing for an application where only one differential pair is needed using DS320PR410. I would like to properly terminate the inputs for the other 3 differential inputs to prevent issues such as noise or excessive power consumption. Please advise on how to properly disable them. Thank you!

    Hi Kevin,

    For termination, please connect unused channel RX through a resistor (49.9 ohm) and capacitor (220 nF) in series to GND. Ensure traces used to connect termination is impedance matched to 50 ohms. TX can be left floating. 

     

    Best,
