Hi all, I'm using DP83822HF in FX-MODE for one-direction data transmission, just for receiving.
I wander can I disconnect TD_P and TD_M pin and pull-up to 3.3V , and saving a fiber.
*The device will receive only UDP message.
*FX-mode have been strapped by hardware, which can be checked OK form register 0x0A.
*Signal detect pin have been pull-up to 3.3V with a 2k resister.
*Auto-nego is disabled.
*I have test 100M-TX mode, when I disconnect TD_P or TD_M, the link status will turn down, and link status led also turn off.
My question: Is this scheme can be realized for a single-direction transmision. If CAN, how can I config the relate register.If NOT, why?
Thank you.
