PMC PAS6301
The PAS6301 is a Gigabit Ethernet Optical Network Unit (ONU)system on a chip dedicated for use in an Ethernet Passive Optical Network (IEEE 802.3ah EPON). The PAS6301 chip integrates the Ethernet Media Access Control (MAC) functionality, EPON protocol management, an advanced L2/3/4 classification engine, a powerful embedded CPU and a glueless interface to an on-board Analog Front End (AFE).FEATURES
● Gigabit Ethernet PON ONU based on 802.3ah standard● Integrated SERDES and CDR for loop timing support ay ,1 4D
● FEC coding for improved link budget ec em VxWorks and a low footprint RTOS Memory Controller Rate Limiter D/S Queue MAC LLID Bridge Security Classifier be An integrated software package provides a complete ONU solution.
● Open Software development platform with support for Linux, r, and downstream and can be configured to operate per priority queue, per the whole ONU, or per VID . An additional mode exists for upstream enabling the rate limitation of multicast and broadcast frames separately. VLAN 20 06 06
● An advanced Rate Limiter which can be operated in both upstream :3 and up to 8MB of bursty traffic protection liu by Optics Control MPCP Engine U/S Queue VLAN Rate Limiter Classifier 10/ 100 MAC lo ad ed 8:
