    摘要: A method for multicasting packets in a passive optical network (PON) residential gateway. The method comprises storing a payload portion of an input packet in a memory; duplicating a header of the input packet to create duplicate headers as the number of destination end-point devices; modifying each of the duplicated header to uniquely designate an output interface of an Ethernet medium access (MAC) adapter coupled to at least one of the destination endpoint devices; passing to the Ethernet MAC adapter its respective modified header together with a pointer to a location of the payload portion in the memory; generating a multicast packet by retrieving the payload portion from the memory and attaching the modified header to the payload portion; and transmitting the multicast packet to the destination endpoint device coupled to the Ethernet MAC adapter.

    摘要: Burst mode clock and data recovery (BCDR) circuit and method capable of fast data recovery of passive optical network (PON) traffic. An over-sampled data stream is generated from an input burst data signal and a phase interpolator generates sampling clock signals using a reference clock and phase information. A phase estimation unit (PEU) determines a phase error in the over-sampled data streams; and a phase retrieval unit sets the phase interpolator with the respective phase information of the input burst data signal prior to reception of the input burst data signal.
