SATA3 Reference Clock
• SATA3_REFCLK[P, N] - SATA3 Controller Reference Clock, Differential
— SoC can function with either Spread Spectrum or non Spread Spectrum
reference clocks.
33.16.3.1 With Spread Spectrum
• PPM Tolerance = 35 ppm
• Cycle-to-Cycle Jitter = 85 ps
• Spread = -0.50%
• Cycle-to-Cycle Jitter = 85 ps
• Spread = -0.50%
33.16.3.2 With no Spread Spectrum
shows the required clock period based on:
• PPM Tolerance = 35 ppm
• Cycle-to-Cycle Jitter = 85 ps
• Spread = 0.00% (no spread spectrum)
• Cycle-to-Cycle Jitter = 85 ps
• Spread = 0.00% (no spread spectrum)
