PB PRS 5G-20G / v0.5 / 05-24-2004
PRS 5G and PRS 20G
Switch Fabric
PRS 5G (PRS C48X) and PRS 20G
(PRS C192X) Switch Fabric Device
Features
• 2.5-Gbps (PRS 5G) and 10-Gbps
(PRS 20G) full-duplex user bandwidth
switch devices with an overspeed of
two towards the backplane
• Embedded IBM 3.2-Gbps SerDes, with
8b/10b coding and XAUI-compliant
high-speed serial links
• PRS 5G (PRS C48X): CSIX-L1 or
PL3-based (POS-PHY Level 3 / OIF-
SPI3-01.0) 32-bit wide interface for
multi-GE / OC-48 network processors
• PRS 20G (PRS C192X): CSIX-L1
64-bit wide or 128-bit wide interface for
a 10-Gbps / OC-192 network
processor or 4x CSIX-L1 or PL3-based
(POS-PHY Level 3 / OIF-SPI3-01.0)
32-bit wide interfaces for multi-GE /
OC-48 network processors.
• PRS 20G (PRS C192X) operation in
subport mode or, in conjunction with
the PRS 80G switch core, in quad
PRS 5G (PRS C48X) mode, for more
integrated line card solutions
• Dual-switch attachment for redundant
switch plane operations (central switch
configurations)
• Highly-efficient multicast and
broadcast mechanism
• Ingress virtual output queuing (VOQ)
per destination port and priority, with
separate multicast queues, preventing
head-of-line blocking
• Up to four levels of traffic priority (CoS)
and four programmable ingress queue
thresholds (ingress CSIX / PL3 flow
control per destination port and
priority)
• Packet scheduling: strict priority
scheduling, credit table (weighted
round-robin), exhaustive highest
priority first
• Implements flow control bit map
mapping to ease adapter redundancy
schemes
• End-to-end packet payload protection,
with optional cyclic redundancy check
insertion
• Internal loop back support for both the
CSIX / PL3 interface and switch
interface
• Hardware compatibility with PRS 80G
switch core device via SerDes
operating at 3.2 Gbps
• Backward compatibility with
PRS 64Gu switch core device via
SerDes operating at 2.5 Gbps
(overspeed factor of 1.6)
• Backward compatibility with
PRS Q-64G switch core device via
SerDes operating at 2.5 Gbps
(overspeed factor of 1.6 for PRS 20G /
PRS C192X, or 6.4 for PRS 5G /
PRS C48X)
Enablement Tools for an
Expedited Time to Market
To facilitate the evaluation and
prototyping of complete solutions,
reference switch boards featuring the
AMCC PRS 5G and PRS 20G,
respectively, are available for installation
in evaluation platforms.
To help reduce development time and
cost, AMCC offers PRS 64Gu, PRS 80G
and PRS Q-64G switch evaluation
platforms, switch core reference
designs, and reference software to
operate switch boards.
To allow system vendors to evaluate
multi-vendor solutions, the PRS boards
and platforms are enabled for
attachment of other suppliers' NPU
platforms. Board design services and
board manufacturing capabilities
complement the AMCC PRS offering.
