Compatible SATA Components and Modes PARAMETER MIN MAX UNIT SUPPORTED Transfer Rates 1.5 3 Gbps Internal Cable - - - YES 8.5.5.3 PCB Stackup Specifications Table 8-21 shows the stackup and feature sizes required for these types of SATA connections. Table 8-21. SATA PCB Stackup Specifications PARAMETER MIN TYP MAX UNIT Number of ground plane cuts allowed within SATA routing region - - 0 Cuts Number of layers between SATA routing area and reference plane - - 0 Layers PCB Routing clearance 4 Mils PCB Trace width 4 Mils 8.5.5.4 Routing Specifications The SATA data signal traces must be routed to achieve 100 Ohms (+/-10%) differential impedance and 60 ohms (+/-10%) single ended impedance. The signal ended impedance is required because differential signals can’t be closely coupled on PCBs and therefore single ended impedance becomes important. 60 ohms is chosen for the single ended impedance to minimize problems caused by too low an impedance. These impedances are impacted by trace width, trace spacing, distance to reference planes, and dielectric material. Verify with a PCB design tool that the trace geometry for both data signal pairs results in as close to 100 ohms differential and 60 ohms single ended impedance traces as possible. For best accuracy, work with your PCB fabricator to ensure this impedance is met. Table 8-22 shows the routing specifications for the SATA data signals. Table 8-22. SATA Routing Specifications PARAMETER MIN TYP MAX UNIT SATA signal trace length (device balls to SATA connector) 3050(1) Mils Differential pair trace skew matching 5 Mils Number of stubs allowed on SATA traces(2) 0 stubs TX/RX pair differential impedance 90 100 110 Ω TX/RX single-ended impedance 54 60 66 Ω Number of vias on each SATA trace 0 Vias SATA differential pair to any other trace spacing 2×DS(3) (1) Beyond this, signal integrity may suffer. (2) Inline pads may be used for probing. (3) DS = differential spacing of the SATA traces. Table 8-23.
