Hi,

I got questions about TX_DEEMPHx pin from my customer.

1. What is the absolute maximum ratings of TX_DEEMPHx pins?

2. It is mentioned that TX_DEEMPHx pin's TYPE are I/PU/PD.

    TX_DEEMPHx pins are both PU and PD, aren't they ?

Thanks 

Kuramochi

    Hello Kuramochi,

    Please see the answers below:

    1) The absolute maximum ratings are defined by VDD1P8 steady-state supply voltage, but those terminals must be working under the recommended operation conditions VDD1P8 (MIN 1.62V, NOM 1.8V, MAX 1.98V)


    2) Yes they are. With no external components, the TX_DEEMPH(1) is PD and TX_DEEMPH(0) is PU, that means that the default de-emphasis is -3.5 dB.

    Regards,

    Gerardo
