Dears,
PN#:DP83848NRTAR
Please help to analyze the problem: When 3516DV300+83848 in CD54 shell, It would fail with 50m CAT7 wire.
1. The following figure are based on the test results of CAT7 network cable of 50 meters;
2, It can be seen that the effect of 83848 is slightly worse than RTL8201 and CPU built-in PHY;
3. The difference between CD54 and CR34 is that CD54 has a 10cm FFC line between the network transformer and the PHY, while CR34 is directly connected on the PCB board.
4. "×" indicates that the network is disconnected.
