Patent ID: 8705608

Claim:
A method in a burst mode receiver to determine the validity of an incoming burst signal, comprising: receiving consecutive pulses of an incoming signal; determining if a first time duration between a signal edge of a first pulse and a signal edge of a second pulse is within a first time range of a predetermined timing separation of a valid burst signal, the first pulse and the second pulse being consecutive pulses; if the first time duration is within the first time range, determining if a second time duration between the signal edge of the second pulse and a signal edge of a third pulse is within the first time range, the second pulse and the third pulse being consecutive pulses; if the second time duration is within the first time range, asserting a signal indicative of a valid burst signal; and if the first time duration is not within the first time range or the second time duration is not within the first time range, deasserting the signal indicative of a valid burst signal.
