PRS Q-80G, PRS C48X, and PRS C192X
Switch Fabric
PRS Q-80G Switch Device,
PRS C48X and PRS C192X Fabric
Interface Devices
The PRS Q-80G device performs the switch
core function, in configurations of two, four, or
eight devices, depending on the switching
capacity needs. The PRS C48X and PRS
C192X devices perform the queuing manager
function of the PRS Q-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.

Highlights –
QoS Enforcement at Media
Speed, Real-Time Traffic Sup-
port, Full Bandwidth Multicast
• Non-blocking, shared-memory,
single-stage switch fabric chip set:
PRS Q-80G cell switch device
providing 80 Gbps of aggregate
switching capacity, PRS C48X and
PRS C192X fabric interface devices
(queue managers)
• PRS C48X and PRS C192X available
in RoHS compliant version for lead
free designs
• Up to 320 Gbps (eight devices) of
full-duplex aggregate user bandwidth
with a per-port overspeed factor of 2
• QoS enforcement at media speed
• Real-time traffic support (guaranteed
precedence of time-sensitive traffic
over other traffic types)
• Multicast and broadcast full bandwidth
support (100% line utilization) while
preserving low switching delay
• Deterministic low latency, typically a
few microseconds for high priority
traffic under worst case conditions
(100% traffic load)
• Traffic scheduling QoS options: strict
priority scheduling, weighted round-
robin, exhaustive highest priority first
• End-to-end, in-band flow control
mechanisms through the switch fabric
• Redundant switch board operations:
hot standby mode, load sharing mode,
maintenance switchover (cell
lossless)
• AMCC SSC software for
configuration, monitoring, and control
of the switch board and AMCC
SWICC software, a PC tool for local/
remote testing (traffic generation,
digital eye, and so on)
• Evaluation switch boards, featuring
two PRS Q-80G (80 Gbps) or eight
PRS Q-80G (320 Gbps)
• System solution with AMCC's nP37xx,
framers, PHYs, and PowerPC
processors, and interoperability with
third-party network processor devices
Scalability and Multiple Port Speeds
The PRS Q-80G switch, in conjunction with the
PRS C48X and PRS C192X fabric interface
devices, provides 80 Gbps (two devices),
160 Gbps (four devices), or 320 Gbps (eight
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 Q-80G enables the design of
single-stage switch fabrics with up to 32 ports
for network processors that support OC-192c,
10-Gbps, and multi-GE applications, or up to
128 ports for network processors that support
OC-48c and multi-GE applications, or any
intermediate mix of those ports.
The PRS Q-80G also has built-in a 40-Gbps
clear channel attachment capability, requiring a
customer ASIC or FPGA to interface with a
40-Gbps protocol engine.
Switch Fabric Solution with Carrier
Class QoS Features for
Applications up to 320 Gbps
The AMCC PRS Q-80G is a switch device for
systems up to 320 Gbps of aggregate user
bandwidth. The PRS Q-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 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 Q-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 Q-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 80-Gbps and
320-Gbps reference switch boards.
RoHS Compliance to Enable Lead
Free Designs
The PRS C48X and PRS C192X fabric
interface devices are available in two versions:
the leaded version, for lead soldering process,
and the version complying with the directive on
the Restriction of the use of certain Hazardous
Substances (RoHS) and enabling lead free
soldering.
QoS Enforcement at Media Speed
The PRS Q-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
