DP83867ERGZR 電路設計差異

1. Each of supply pins should have dedicated 1uF and 100nF decap (pins 19,30,41,3,9,6,24,31,42,13,48).

2. Board ground and connector ground should be separated by 1Mohm resistor in parallel with 4.7nF cap.

3. Please do not put capacitor on RBIAS, connect a 11kohm 1% tolerance resistor between RBIAS pin and GND. 

4. Add a 1uF pulldown capacitor on the RST pin

5. Only need 2.2k pullup on MDIO, no need to have pullup on MDC
