DP83TC811S-Q1: Disable 16, 27, 28 pin

Part Number: DP83TC811S-Q1

Hi Team,

When I'm using DP83TC811S with SGMII, does is means the RGMII is absolutely shunt down? Because I found there are always 25MHz output form 16pin CLKOUT, 27pin RX_CLK,28pin TX_CLK. Can I disable these three pins?

We are looking into this but unfortunately there will be delay in response this time. We will get back to you by early next week.

Hello Frank,

As we are away on Christmas break so could not get chance to verify it in the lab but following inputs should help :

You may disable clkout by writting register<x0463> = x0006.

Tx_clk should not be switching in Sgmii mode.

Need to confirm if Rx_clk is switching in Sgmii mode and find if any setting is available to shut it off.

Regards,

Vikram
