DP83TC812EVM-MC: media converter working

DP83TC812EVM-MC: Remote control Media converter's wake up , sleep

Part Number: DP83TC812EVM-MC
Other Parts Discussed in Thread: USB-2-MDIO

I have DP83TC812EVM-MC 2 Boards.

Already tested wake-up, sleep test case via user manual , Ther are working well.

(pull the wake pin high using the available jumper on the EVM, and send Reg 0x018c, 0002 wiring via USB-2-MDIO Tool) 

But in this case, Master EVM was going to sleep

so, next wake-up I had to put the wake pin high

How can I do wake up, sleep of EVM remotely(by SW).

Wanted Test Case 

1. Set Master , Set Slave

2. Master send Wake up message to Slave Board. (by SW)

3. Master send Sleep message to Slave Board. (In this time Master does not go to sleep mode, becuase I don't want to lost USB Connection )

4. Master send Wake up message to Slave Board again. (by SW)

    Hi Jeehoon,

    Unfortunately this exact test case is not possible, as remote wake requests via register access cannot be performed unless the wake pins of both PHYs are connected.

    If the wake pins are connected, then a manual wake forwarding request ( 0x184[4] = '1' ) will transmit a high pulse on the wake pin and wake up any other PHYs with wake pins connected.

    Otherwise, 0x18c[2] is used for remote sleep request, and pulsing the wake pin via the EVM jumper is the recommended method for wake up. 

    Thank you,

    Evan

    Hi Evan

    DP83TC812EVM-MC is just support 100Mbps, but I need 1000/100 Mbps Speed. (TC10 Support)

    Could you recommend phy chipset instead of DP83TC812?  

    if TI does not have a chipset, recommend other company chipset? 

    I will have a plan to design it ,just to change phy chipset of DP83TC812EVM-MC

    Thanks.

    Hi Jeehoon,

    I recommend reaching out to your local FAE to connect you with marketing for this query.

    Thank you,
