Part Number: DP83825I
Hi team,
Regarding "8.2.2.3 TPI Network Circuit" in the DP83825I Low Power 10/100Mbps Ethernet Physical Layer Transceiver datasheet (Rev. C):
1. Is it acceptable to use 75Ohm + 1000pF for C38 instead of 0.01uF? (I recall seeing 75Ohm + 1000pF specified in another one of your application notes.)
2. Is my understanding correct that C41 and C44 (0.1uF + 1uF) do not need to be connected to 3.3Vcc?
3. Is it correct that 50Ohm termination resistors for the TD and RD signals are not required? (These were implemented in the previous model, DP83848.)
My customer will use the following pulse transformer: Sumida CLP0612
Best regards,
Kazuki Itoh
