Notes:
1.
This parameter indicates the total sampling error of Virtex-5 FPGA DDR input registers across voltage, temperature, and process. The
characterization methodology uses the DCM to capture the DDR input registers’ edges of operation. These measurements include:
- CLK0 DCM jitter
- DCM accuracy (phase offset)
- DCM phase shift resolution
These measurements do not include package or clock tree skew.
2.
This parameter indicates the total sampling error of Virtex-5 FPGA DDR input registers across voltage, temperature, and process. The
characterization methodology uses the BUFIO clock network and IODELAY to capture the DDR input registers’ edges of operation. These
measurements do not include package or clock tree skew.

1.1
First version posted to the Xilinx website. Minor typographical edits. Revised design software version on
05/24/06
1.2
Added register-to-register parameters to
Table 52.08/04/06
1.3
Added VDRINT, VDRI, and CIN values to Table 3. Added HSTL_I_12 and LVCMOS12 to
Table 7 and renumbered the notes.
Removed pin-to-pin performance (Table 12). Updated and added values to register-register
Updated the speed specification version above
Table 54.Added to
Table 56 the I/O standards: HSTL_II_T_DCI, HSTL_II_T_DCI_18, SSTL2_II_T_DCI, and
SSTL18_II_T_DCI.
In Table 74, changed FVCOMAX, removed TLOCKMIN, and revised TLOCKMAX values, also removed note pointing to Architecture Wizard.
