WebThe direct translation between LVDS and PECL/LVPECL signals is not possible. This is because the LVDS output common mode and differential voltage are not compatible with PECL input levels. Devices like MC100(LV)EL17 should be used to translate these signals. Figure 8: Interfacing LVDS to PECL/LVPECL Using the MC100(LV)EL17 device 9. WebAug 22, 2014 · In this final example, we did not have to use AC-coupling capacitors to reset the common mode voltage as the ration of R1 to R3 and R2 to R4 sets the amount of attenuation applied to the common-mode signal. AC-coupling is still an option at this point though, if the sub-LVDS receiver requires it.
