5 Gb/s burst-mode clock phase aligner with (64, 57) Hamming codes for GPON applications

We demonstrate a 5 Gb/s burst-mode receiver (BMRx) featuring automatic phase acquisition using a clock phase aligner, and forward-error correction using (64, 57) Hamming codes. This BMRx provides instantaneous (0-bit) phase acquisition with packet-loss ratio < 10-6 and bit-error rate < 10

for any phase step (plusmn2pi rads) between consecutive packets. Our design is based on an oversampling local oscillator operated at twice the bit rate and a phase picking algorithm.
