Transmit Data In (Note 2) 2 VeeT Transmitter Ground Notes: 1. RD+ and RD are AC coupled 1Ω differential lines which should be terminated with 1Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 37 and 2 mv differential (185 1 mv single ended) when properly terminated. 2. TD+ and TD are ACcoupled, differential lines with 1Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 5 24 mv (25 12 mv singleended), though it is recommended that values between 5 and 12 mv differential (25 6 mv singleended) be used for best EMI performance.
