Product Specification

Extended LVDS DC Specifications (LVDSEXT_25)
LVPECL DC Specifications (LVPECL_25)
These values are valid when driving a 100
Ω differential load
only, i.e., a 100
Ω resistor between the two receiver pins.
The VOH levels are 200 mV below standard LVPECL levels
and are compatible with devices tolerant of lower com-
mon-mode ranges. Table 11 summarizes the DC output
specifications of LVPECL. For more information on using
LVPECL
, see the Virtex-4 FPGA User Guide: Chapter 6,
SelectIO Resources.
