TDA2E: TDA2x Ethernet direct connection problem

Dears,

Our project uses TDA2x and TC397 Ethernet direct connection, with TDA2x internal switch as shown in the screenshot.

My question is whether the connection between TDA itself and the external environment should directly use route A or route B?

Hi,

Is it related to H/W Schematic Query? If so, can you please share the schematics with us for review.

Hi,

From the schematic it seems RGMII1 of TDA2 is connected to Marvell PHY.

Hi,

TDA and MCU is exchanging data through line B? RGMII 0?

Yes, from above TDA2 RGMII0 is connected to TC397.

As TDA2 has two Port Gigabit Ethernet Switch out of which Port-1 (RGMII0) connected TC397, Port-2 (RGMII1) is connected to 88Q1010 Marvell PHY.
