These values represent the worst-case skew between any two SelectIO resources in the package: shortest delay to longest delay from Pad to Ball.
Some of these devices are available in both Pb and Pb-free (additional G) packages as standard ordering options.
LXT devices are not available with a -1L speed grade.
This parameter indicates the total sampling error of Spartan-6 FPGA DDR input registers, measured 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.
This parameter indicates the total sampling error of Spartan-6 FPGA DDR input registers, measured across voltage, temperature, and process. The
characterization methodology uses the BUFIO2 clock network and IODELAY2 to capture the DDR input registers’ edges of operation. These
