Product Overview
The PAS65xx family is an EPON Optical Network Unit (ONU) System-on-a-Chip (SoC) device family, dedicated for use in an Ethernet Passive Optical Network (IEEE 802.3ah EPON). The PAS65xx devices are optimized for building EPON ONU in a Single Family Unit (SFU), a Multi-Dwelling Unit (MDU), or similar configuration. The PAS65xx device family integrates the EPON SERDES and CDR, Optical Analog Front End (OAFE) (PAS651x only), EPON and Ethernet Media Access Control (MAC), EPON protocol management, an advanced classification and packet processing engine and traffic manager, a powerful embedded ARM926 CPU, a dedicated DSP for four channel VoIP processing (PAS65x2 only), and Gigabit Ethernet (GbE) user interfaces. The device also supports Time of Day (ToD) and Synchronous Ethernet (SyncE) time synchronization for cellular backhaul applications, and Power Save modes for reduced power consumption. PAS65xx is provided with an integrated software package, Application Program Interface (API) and application suite providing a complete ONU solution.
  • Full IEEE 802.3ah EPON ONU functionality with comprehensive software package, compatible to PMC-Sierra's PAS6301 ONU for easy migration
  • Support for various markets and operator specifications (CTC, NTT, KT, US MSO)
  • Versatile to all FTTH/FTTB ONU applications
  • Form factor and RBOM optimization featuring small size package, small PCB footprint, and low cost RBOM
  • Advanced classification engine with support for VLAN, IP, TCP & UDP to provide true "triple-play" services
  • Advanced QoS features: flexible traffic management to enable queuing per user/service, scheduling, shaping and policing
  • Advanced switch management capabilities including a standard MII interface supporting various external switches
  • Low power consumption: 1 W typical at 1 Gbit/s throughput
  • Power down modes enabling up to 80% ONU system power reduction
  • Field proven Interoperability using EPON software stack from PMC-Sierra
