Hello,

Please refer to this Open Alliance application note where we recommend 100 ohms on R_Xi:

Hi Avtar

Thanks for your reply.

It only told me to use 100 ohms, i still do not understand why, like which test item may be fail with 0 ohm?

Bruce

Hello Bruce,

These are rule of thumb recommendation for passing Open Alliance compliance testing, we do not have exact data on what tests will fail if using 0 ohm R_XI but 100 ohm is recommended. Are compliance tests failing currently when using 0 ohms R_XI?
