17.5 Common High-Speed Interface
Requirements
The following table describes the common high-speed interface requirements.
Table 17-2. Common High-Speed Interface Requirements
Parameter Requirement Units Notes
Common-mode Choke (Not recommended – only used if absolutely required for EMI issues)
Preferred device Type: TDK ACM2012D-900-2P. Only if
needed. Place near connector. Refer to
Common Mode Choke Requirement
section.

General
Routing over Voids Routing over voids not allowed except void around device ball/pin the signal
is routed to.
Noise Coupling Keep critical high-speed traces away from other signal traces or unrelated
power traces and areas or power supply components
The following figures show the common high-speed interface signal routing requirements.
