LVPECL DC Specifications
These values are valid when driving a 100 Ω differential load only, i.e., a 100 Ω resistor between the two receiver pins. The
V_OH levels are 200 mV below standard LVPECL levels and are compatible with devices tolerant of lower common-mode
ranges. Table 37 summarizes the DC output specifications of LVPECL. For more information on using LVPECL, see [Ref 1].
