ETHERNET : Design notes and Layout Guidelines:
1- Ethernet Data DP/DN traces must be routed as 100 Ohms Differential pairs.
2- Match trace lenght of DP/DN differential pairs. 100 mils max within a pair.
3- Route differential pairs above the GND plane. Do not split the GND plane under differential pairs.
4- Use minimum number of VIA.
5- When possible, use higher clearance distance between differantials pairs and any others traces (>15 mils).
6- For fanout facility, all the ethernet terminations can be place close to the connector.
7- Use a 15 mils trace to route 2.5V.
8- Place EPHY_RDAC resistor close to BCM7440.
SATA : Design notes and Layout Guidelines:
* SATA speed is 1.5Gbs, keep traces as short as possible.
1- SATA Data DP/DN traces must be routed as 100 Ohms Differential pairs.
2- Match trace lenght of DP/DN differential pairs. 20 mils max within a pair.
3- Route differential pairs above the GND plane. Do not split the GND plane under differential pairs.
4- Use minimum number of VIA.
5- When possible, use higher clearance distance between differantials pairs and any others traces (>15 mils).
6- Place series capacitors close to connectors.
7- Place SATA 25MHz xtal and passive component close close to BCM7440.
