This video shows how to solve design challenges on interfacing Ethernet PHY
with application processors or microcontrollers. It covers the fundamentals
of Ethernet design, provides an example based on a TI reference design that
integrates the Sitara™ AM5728 processor and the DP83867 Gigabit Ethernet
PHY and provides an overview of other TI solutions that can be used to
resolve Ethernet PHY design challenges.

Thanks, this just made my job a whole lot easier

At the start of the video, RGMII was described as it takes 125MHz Clock freq whereas later we were designing with a clock input of 25MHz, I just got confused. is there anything I missed, Thanks

Hello this clock is usually generated internally from the 25Mhz clock (probably from a PLL) or accepted from an external source (Such as a MAC) as a125MHz signal input signal.

19:34: for what are the "magnetics"?

[@connerblah]

They're isolation components. Ethernet spec requires galvanic isolation from the cable. They're often built into the RJ45 jack. There's a blurry image at 4:10, but RJ45 jack data sheets (like the HY931147C) have more readable schematics.

RGMII has 4 tx and 4 Rx lines
