Notes to Table 1â31:
(1) The jitter numbers for XLAUI/CAUI are compliant to the IEEE P802.3ba specification.
(2) Stratix IV GT transceivers are compliant to the XFI datacom transmitter jitter specifications in Table 9 of XFP Revision 4.1.
(3) Contact Altera for board and link best practices at BER = 1E-15.
Table 1â32 lists the SFI-S transmitter jitter specifications for Stratix IV GT devices.

Notes to Table 1â32:
(1) Dedicated refclk pins were used to drive the input reference clocks.
(2) The jitter numbers are valid for stated conditions only.
(3) Two hundred channels were characterized to derive the mean transmitter jitter specification of 0.23 UI. The maximum jitter across the 200 units
characterized was 0.30 UI.
(4) Contact Altera for board and link best practices at BER = 1E-15.
