eDP 走线请注意:
- eDP 信号的参考时钟建在数据中,在接收端还原出时钟信号,所以四组数据差分线对组间不做等长,只需做组内等长处理;
- 为抑制电磁辐射,eDP信号建议PCB内层走线,并保证走线参考面是一个连续完整的参考面,不被分割,否则会造成差分线阻抗的不连续性并引入外部噪声对的影响。如在PCB表层走线,请注意用地线做包地处理;差分对之间不需要伴随地走线;
eDP走线要求如表:
参数 | 要求 |
Trace Impedance | 100Ω ±10% differential |
Max intra-pair skew | < 4 ps |
Max trace length on carrier board | < 6 inch |
Minimum pair to pair spacing | > 3 times the width of the trace.Try to increase Spacing between pairs whenever it is possible. |

HDMI走线请注意:
- HDMI TX信号的参考时钟为HDMI TXC,所以包括时钟在内的四组差分对都需要做等长处理;
- HDMI信号需要保证走线参考面是一个连续完整的参考面,不被分割, 否则会造成差分线阻抗的不连续性并引入外部噪声对的影响。在PCB表层走线请注意用地线做整组包地处理; 差分对之间不需要伴随地走线;
- HDMI信号可以直接顺序扇出到HDMI连接座,走线中应该尽可能的减少换层过孔,过孔会造成线路阻抗的不连续;如果因为模具结构无法避免换层,建议将换层的阻抗变化控制在10%以内,并在每对换层的差分对旁边就近安排一个GND过孔用于信号回流路径的换层;
- ESD器件靠近HDMI连接座放置;
- 使用带屏蔽层的HDMI线缆,能有效改善EMI问题;
HDMI走线要求如表:
