1. Measured at receiver
2. 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. For recommended operating conditions, see Table 3.
3.19.11 XFI interface
This section describes the XFI clocking requirements and its DC and AC electrical
characteristics.
3.19.11.1 XFI clocking requirements for SDn_REF_CLKn_P and
SDn_REF_CLKn_N
Only SerDes 1 (SD1_REF_CLK[1:2]_P and SD1_REF_CLK[1:2]_N) may be used for
SerDes XFI configurations based on the RCW Configuration field SRDS_PRTCL.
For more information on these specifications, see SerDes reference clocks.
3.19.11.2 XFI DC electrical characteristics
This section describes the DC electrical characteristics for XFI.
3.19.11.2.1 XFI transmitter DC electrical characteristics
This table defines the XFI transmitter DC electrical characteristics.
