3. Total jitter is composed of three components: deterministic jitter, random jitter, and single frequency sinusoidal jitter. The
sinusoidal jitter may have any amplitude and frequency in the unshaded region of Figure 44. The sinusoidal jitter component
is included to ensure margin for low frequency jitter, wander, noise, crosstalk, and other variable system effects.
3.19.7 Aurora interface
This section describes the Aurora clocking requirements and its DC and AC electrical
characteristics.
3.19.7.1 Aurora clocking requirements for SDn_REF_CLKn_P and
SDn_REF_CLKn_N
Only SerDes 2 (SD2_REF_CLK[1:2]_P and SD2_REF_CLK[1:2]_N) may be used for
SerDes Aurora configurations based on the RCW Configuration field SRDS_PRTCL.
Aurora is not supported on SerDes 1-3.
For more information on these specifications, see SerDes reference clocks.
