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
