Applications of Serial ATA Tools
• SERDES,
• Host Bus Adaptors,
• Switches,
• Hard Drives,
• motherboards,
• Cables,
• Bridges,
• clocks
• PLLs
The SATA standard defines a jitter generation specification profile. This tool automates these
measurements and provides pass/fail results.
Serial ATA II Hardware Clock Recovery Compliance Tool
This tool is for usage models 1x, 2x and utilizes the Wavecrest Multi-rate Clock Recovery option. The
SATA II Electrical Specification Rev. 1.0 describes these usage models:
Gen1x: Extended Length 1.5 Gb/s Electrical Specification or "Gen1x": These are newly developed
electrical specifications, described here, aimed at 1.5 Gb/s links in "long" backplanes and
system-to-system applications. These specifications are based upon Serial Attached SCSI
Electrical specifications (CT/CR specifications as called out in SAS).
Gen2x: Extended Length 3.0 Gb/s Electrical Specification: These are newly developed electrical
specifications, described here, aimed at 3.0 Gb/s links in "long" backplanes and system-to-
system applications. These specifications are based upon Serial Attached SCSI Electrical
specifications (CT/CR specifications as called out in SAS).
A number of changes in methodology have been implemented in SATA Gen 2 relative to SATA Gen 1.
Most significant is the adoption of a clock recovery model. This model requires measurement of jitter:
baud/1667 for 2x and 1x usage models.
