Compliance Test and Measurement Load
The AC timing and voltage parameters must be verified at the measurement point, as specified within
0.2 inches of the package pins, into a test/measurement load shown in Figure 44.
NOTE
The allowance of the measurement point to be within 0.2 inches of the
package pins is meant to acknowledge that package/board routing may
benefit from D+ and D– not being exactly matched in length at the package
pin boundary. If the vendor does not explicitly state where the measurement
point is located, the measurement point is assumed to be the D+ and D–
package pins.

16 Serial ATA (SATA)
This section describes the DC and AC electrical specifications for the serial ATA (SATA) of the
MPC8377E. Note that the external cabled applications or long backplane applications (Gen1x and Gen2x)
are not supported.

Requirements for SATA REF_CLK
The reference clock is a single ended input clock required for the SATA interface operation. The AC
requirements for the SATA reference clock are listed in the Table 54.
