The PAS740x device family is Microsemi's second generation GPON ONT System-on-a-Chip (SoC) device family, dedicated for use in GPON (ITU-T G.984) networks. The PAS740x devices are optimized for building a high-performance, extremely low power and low cost GPON ONT in Single Family Unit (SFU), Multiple Dwelling Unit (MDU), or similar configurations. The PAS740x devices integrate GPON SERDES, MAC and packet processing functions, together with an integrated ARM926 controller, Gigabit Ethernet (GbE) user interfaces, a TDM interface, and a dedicated DSP for VoIP processing (on PAS7401V only).The PAS740x device family is based on Microsemi's field proven GigaPASS networking architecture, which provides marketleading throughput and quality of service (QoS). The PAS7401/7401V provide simultaneous, sustained 2 Gbit/s downstream and 1.244 Gbit/s upstream throughput at all packet sizes. The GigaPASS networking engine provides TR-101 compliant networking features, compliant with FSAN CTS specifications, including 802.1p/q bridging, packet classification, filtering and queuing, traffic shaping, and policing. PAS740x is provided with a comprehensive, turnkey-level software package which includes:
