SGMII mode initialization sequence is very similar to TBI mode initialization.
Interface
initialization sequence is shown in
15-206
Initialize SerDes to select SGMII. The initialization sequence should be prepended with SerDes initialization.
Mode.”Additional initialization is required for the SerDes. An example of SGMII mode
set source clock divide by 14 for example to insure that MDC clock speed is not greater than 2.5 MHz
