Does anyone know this chip is ATMega328 or ATMega328P?
Heading and description indicates ATMega328 but in the product picture which shows like ATMega328P.(as a general rule we can only believe the product descriptions rather than picture while shopping anywhere :))

Now I understand why 6.8nF series capacitors used in ‘tristanseifert’ schematic. he is using ENC424J600 and its datasheet specifies to use series capacitors in RD line. It also specify to use a resistance in TD center tap.
So magjack schematics also depended on the ethernet controller specification. I’m using ENC28J60 and I need to update my pinouts in which RD and TD pins where interchanged according to an different version of magjack reference rather than this. I will come up with the result later. Thanks to ‘tristanseifert’ and ‘Lauszus’
Lauszus Could you kindly post your schematics with interfacing magjack to the ethernet controller? above given link only indicates magjack pins. The below post by ‘tristanseifert’ with link here does include 6.8nF series capacitors in RD(rx) pins. is this necessory? or you managed without these series capacitors? also there are differences in center tap connections. Your’s seems to be simpler. It will be much helpful if you could post the interfacing schematics with all resistors and capacitors used.
