AC Characteristics
Specifications are guaranteed over the recommended operating conditions listed in
Table 11 on page 11
.
1.
Refer to Application Note AN-37 for differential measurement techniques.
2.
Output swings are higher than the Serial ATA 1.0 specification to compensate for anticipated PCB or connector losses.
