15.6 Common High-Speed Interface

Requirements

Table 15-2 provides the common high-speed interface requirements.

Table 15-2. 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. See Figure 15-2

Location - Max distance from to adjacent discontinuities

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/areas or power supply components
