DP83TG720S-Q1: Check a Schematic of DP83TG720S-Q1

Part Number: DP83TG720S-Q1

Hi. Team

I am going to apply DP83TG720S-Q1 to my project.
I tried to compose the Ethernet circuit referring to the EV circuit diagram.

I am trying to do 1G Ethernet communication using Matenet of TE.

I'm asking for advice on whether there are any problems with the schematic I wrote.

thanks

Hello,

The image attached is extremely small and I cannot see any of the components. Are you able to attach a larger image or more preferably, a searchable pdf? This will make the review easier.

Thank you,

Nikhil Menon

Hi Cho,

Please find below my schematic feedback:

Decoupling caps: recommend adding 10nF per pin rather than per supply. Review Section 9 in datasheet.
Clock: ok
INH: ok
Wake: ok, ensure driven high during normal operation
VSLEEP: ok
INT: ok
Reset: ok, ensure drive high during normal operation
LEDs: ok
MDC: ok
MDIO: ok
Straps: 4.7k is not a recommended strap value. Please review Section 7.5 in the datasheet
STRP_1: 10k is not a recommended strap value, please review Section 7.5 in the datasheet.
MDI: Recommend replacing R225 with 100k. Review Section 8 in datasheet.
MAC interface: ok

Please let me know if you have any further questions. Else, I will close this thread.

Thank you,

Nikhil Menon
