The SATA data signal traces are edge-coupled and must be routed to achieve exactly 100 Ohms differential impedance. This is impacted by trace width, trace spacing, distance between planes, and dielectric material. Verify with a proper PCB manufacturing tool that the trace geometry for both data signal pairs results in exactly 100 ohms differential impedance traces. Table 6-47 shows the routing specifications for the data and REFCLK signals.
| PARAMETER | MIN | TYP | MAX | UNIT |
|---|---|---|---|---|
| Device to SATA header trace length | 7000 | Mils | ||
| REFCLK trace length from oscillator to Device(3) | 2000 | Mils | ||
| Number of stubs allowed on SATA traces | 0 | Stubs | ||
| TX/RX pair differential impedance | 100 | Ohms | ||
| Number of vias on each SATA trace | 3 | Vias (1) | ||
| SATA differential pair to any other trace spacing | 2*DS (2) |
