AC coupling a 2.5V LVPECL signal to a differential receiver can be accomplished using a small number of passive components. In this example, the receiver is assumed to be high input impedance without built-in matched load termination. The DC offset bias is assumed to be handled within the receiver. Although the R1 and R2 are not required, if the board space is available, it is recommended to provide R1 and R2 spare footprint. The R1 and R2 footprint can be used for oscillation prevention if needed. It can also be used for DC offset adjustment, if needed, for some receivers with un-clear DC offset requirement. See the solution below. For other questions not addressed by the Knowledge Base, please submit a technical support request.
