Agenda

1. STA presentation (Marty)

Comments (Alvin)
Additional comments

2. 10-meter cable characteristics (Fromm)

Do the characteristics work at 3 Gbps with no equalization?
Equalization required for 6 Gbps?
Format for specification same as previous external cables?

3. Spread spectrum clocking

5000 ppm was used for SATA 1.5Gbps, could be 1250 or 1000 ppm for 6 Gbps 
since it is proportional to frequency?

Jitter measurement concern.
Require turning off to measure jitter?
Does this introduce an EMI compliance issue?

4. Since StatEye is not designed for 8b/10b encoding, should it be 
referenced in the PHY specification?

5. What amount of time is required for equalization tuning?
