Part Number: TDA4VM
There are two SOC's on my customer's board: TDA4VM and another SOC.
Customer wants to use MAC-to-MAC connection between these two SOCs for high speed communications.
current idea: one RGMII port of CPSW9G connect to the RGMII port of the other SOC, without going through the Ethernet PHY.
This will save the PHY cost.
Is there any information we can share regarding this kind of application?
TDA4x MAC to MAC has been used in many other customer boards. The TI CPSW9G driver (EthFw) supports MAC to MAC.
For HW information & clocking consideration, I believe you can follow the RGMII 2.0 specification.
Also, I will loop in TI EVM experts in case they can help.

Many thanks for your great help.
regarding the schematics:
Are the blow connections enough?
TDA4 CPSW9G port MAC
TDA4 => SoC-2
SoC-2 => TDA4
In reply to Peter Li79:
Yes - the connections shown should be correct.
