and PRS C192X) available in RoHS
compliant version for lead free
designs
• 40 Gbps or 80 Gbps of full-duplex
aggregate user bandwidth with a
per-port overspeed factor of two

PRS 80G Switch Device, PRS C48X
and PRS C192X Fabric Interface
Devices
The PRS 80G device performs the switch core
function, in configurations of one or two
devices, depending on the switching capacity
needs. The PRS C48X and PRS C192X
devices perform the queuing manager function
of the PRS 80G-based switches. An adapter
card can be equipped with either a PRS C48X
interfacing a 2.5-Gbps / OC-48 network
processor or a PRS C192X interfacing a
10-Gbps / OC-192 network processor or up to
four 2.5-Gbps / OC-48 network processors.
Switch Fabric Solution with Carrier
Class QoS Features for
Applications up to 80 Gbps
The AMCC PRS 80G is a switch device for
systems in the range of 20-to-80 Gbps of
aggregate user bandwidth. The PRS 80G is a
cell switch, shared-memory device, which
provides 80 Gbps of switching capacity. It uses
.13-micron technology and embedded
3.2-Gbps SerDes to deliver 40 Gbps (one
device) or 80 Gbps (two devices) of user
bandwidth with an overspeed factor of two.
Along with the AMCC PRS C48X and
PRS C192X fabric interface devices, the
PRS 80G addresses the critical QoS needs of
a wide range of highly demanding applications
that handle any mix of real-time and best effort
traffic in the WAN multi-services, Wireless
Infrastructure, Metro Ethernet, Enterprise, and
TDM spaces. The PRS 80G provides low
latency, carrier class QoS and full bandwidth
multicast to efficiently handle real-time traffic
(including TDM) and enable convergence of
voice, video, and data traffic over a single
network infrastructure. It fits the requirements
of the new carrier services, while leveraging
previous carrier investments by providing the
capability to switch IP and TDM traffic
concurrently on the same platform.
The PRS 80G is an integral part of a complete
system solution with AMCC's nP37xx
integrated network processor and traffic
manager products, framers, PHYs, PowerPC
processors, and software. To facilitate the
evaluation and prototyping of complete
solutions, AMCC also offers an 80-Gbps
reference switch board, as well as ATCA
Switch boards, featuring the AMCC PRS 80G.
Scalability and Multiple Port
Speeds
The PRS 80G switch, in conjunction with the
PRS C48X and PRS C192X fabric interface
devices, provides 40 Gbps (one device) or
80 Gbps (two devices) of full-duplex aggregate
user bandwidth with an overspeed factor
per-port of two to match wire-speed
requirements for all possible traffic patterns,
with all line protocols.
The PRS 80G enables the design of switch
fabrics with up to 32 ports for network
processors that support OC-48c and multi-GE
applications, or up to eight ports for network
processors that support OC-192c, 10-Gbps,
and multi-GE applications, or any intermediate
mix of those ports.
QoS Enforcement at Media Speed
The PRS 80G enables full bandwidth
utilization of the media connected to the
payload boards, and still maintains high QoS
performance:
• End-to-end flow control mechanisms
through the switch fabric, and
programmable flow control thresholds
(including multicast), enabling 100%
utilization of the media bandwidth while
maintaining low jitter
• Natively multicast switching technology,
enabling full bandwidth multicast while
maintaining low switching delay
