PM3386
DUAL GIGABIT ETHERNET CONTROLLER
5 APPLICATION EXAMPLES
The PM3386 S/UNI-2xGE is applicable to equipment implementing high density
Gigabit Ethernet interfaces. The PM3386 is a dual channel SERDES and GMAC
with embedded FIFOs that provides a high density and low power Gigabit
Ethernet solution for direct connection to electrical optical modules. Alternatively,
a GMII interface is provided for connection to copper Gigabit Ethernet physical
layer devices.
On the system side, the POS-PHY Level 3 (32 bit synchronous FIFO style
interface clocked up to 104 MHz) allows a common connection to higher layer
devices. A common system interface simplifies multi-service equipment utilizing
some or all of the following physical layer options:
• OC-48 POS/ATM
• 4xOC-12 POS/ATM
• 16xOC-3 POS/ATM
• Channelized POS/ATM
• High density DS3
• Gigabit Ethernet
The PM3386 is particularly suited for the following applications:
• Core Routers
• Edge Routers
• Enterprise Edge Routers
• Multi-Service Switches/Routers
• SONET/SDH Transport Muxes
These applications require various interfaces (Gigabit Ethernet, ATM, POS, DS3)
which use the POS-PHY Level 3 interface. Service cards for various physical
layer options can re-use upper layer devices and board design to improve time-
to market. The use of Gigabit Ethernet within Internet points of presence
(POPs), Super POPs and Transport POPs is increasing due to the requirement
of inexpensive high-speed Layer 2 interconnect. Thus, connections between
