Popis:	In this paper, we demonstrate a 5/10-Gb/s burst-mode clock and data recovery circuit (BM-CDR) for passive optical network (PON) applications. The BM-CDR is based on a phase-tracking oversampling (semiblind) CDR circuit operated at twice the bit rate and a clock phase aligner that makes use of a simple phase-picking algorithm for automatic clock phase acquisition. The design provides low latency and fast response without requiring a reset signal from the network layer. We experimentally test the proposed BM-CDR in a 20-km PON uplink. The BMCDR achieves a bit error rate (BER)
