Abstract
A method for enabling AC coupling or DC coupling when receiving burst data signals comprises generating a hold-over pattern, wherein the hold-over pattern is a AC balanced pattern when an AC coupling is required and a low-logic value signal when a DC coupling is required; inputting the generated hold-over pattern to an AC coupling circuit, when no burst data signal is received; inputting only a received burst data signal to the AC coupling circuit, during the reception of such signal; and upon receiving of the entire burst data signal, generating a reset signal causing to input the generated hold-over pattern to an AC coupling circuit.
