RUBICON-LH
10GE & OC192/48/12/3 DW/FEC/PM and AsyncMap Device with Strong FEC
Part Number S19227PBI-2
Product Brief
Revision 1.0, March 2006
Enhanced Gain Forward Error Correction with G.709 ODU
• 10.71, 10.66, 11.1, 11.27Gbps enhanced FEC with >8dB cod-
ing gain.
• G.709 overhead processing and nominal rate expansion.
• Comprehensive channel statistics gathering.
• Corrected bits, bytes.
• Corrected zeros, ones (with outputs).
• Uncorrectable sub-frame count.
The Rubicon-LH device is capable of running both these gains
simultaneously, providing a superb single chip transponder solu-
tion for standard gain to enhanced gain networks. Note that the
Rubicon-LH will employ the same industry leading EFEC code
that was used in the AMCC Niagara device, making these devices
totally compatible.
DATA INTERFACES
Both the Client and Network interfaces are SFI-4 compliant. Data
is transferred as 16-bit LVDS parallel data with a synchronous
clock. For 10 Gbps applications, both the Client and Network
interface rate can vary between 622 Mbps and 705 Mbps, for an
aggregate bandwidth of 9.95 Gbps to 11.28 Gbps. The defined
low end of the parallel LVDS interface is 31.25 Mbps (across 4
bits of the interface) for an aggregate bandwidth of 125 Mbps. The
device supports OC192/STM-64, ITU G.709 OTU-2, ITU-G.709
ODU-2, or proprietary direct map (into ODU-2) data up to a client
rate of 10.519 Gbps.
Broad Interface Compatibility
• 16-bit 622 Mbps LVDS interface (MSA compliant) 10 Gbps
interface.
• Compatible with AMCC HUDSON, GANGES, KHATANGA,
COLUMBIA, MAROS, MEKONG, NIAGARA, S3091/92,
S3097/98, S19235, S3394 and S3485.
Client and Line side loopback
• Client side and line side loopback on the Rubicon.
Support For System Test and Diagnostics
• Can synthesize SONET frame.
• Error injection capability for verification of remote error report-
ing.
• Test-set compliant pseudo-random sequence generation/anal-
ysis.
CLIENT PERFORMANCE MONITORING
A SONET/SDH performance monitor supporting OC192/48/12/3
and SDH64/16/4/1 rates is provided to perform optional-section
and limited-line termination functions. TOH for the SONET signal
is dropped and added. On chip processing of the critical TOH
functions, such as B1, B2, J0, is provided to enable functioning as
a SONET/SDH network element. The performance monitor may
also be configured to provide non-intrusive monitoring while trans-
parently passing through the received signal with no overwrite.
The 10 Gbps signal and the 2.5 Gbps signal may be synchro-
nously or asynchronously mapped into the ODU-2 and ODU-1
payloads, respectively. FEC parity check bytes are then optionally
added to form the OTU-2 or OTU-1. The device can also output
the OTU-2 or OTU-1 with no parity check bytes. In the receive
direction, data is de-mapped from the OTU-2 or OTU-1 and con-
trol signals are provided to enable timing regeneration of the client
10 Gbps or 2.5 Gbps signal.
When operating in the ITU G.709 OTU-2/OTU-1 or ODU-2/ODU-1
mode, the SONET monitors can be bypassed. Unlike the Niagara
device, the Rubicon-LH provides the capability for intrusive
SONET/SDH performance monitoring inside the OTN frame. On-
chip processing of the G.709 overhead is provided to enable sin-
gle chip G.709 section termination. G.709 Overhead can be added
or dropped as required. The remapping that is required for syn-
chronization of asynchronous ODU-1 signals is supported.
Client-signal monitoring for 8B/10B encoded data is also pro-
vided, as well as 64B/66B monitoring for 10GE-LAN traffic. A full
10GE-LAN MAC is also included in the Rubicon-LH device to sup-
port extensive 10GE monitoring.
General Purpose Processor Interface
• Glueless 16-bit interface to MPC860, 25 MHz to 66 MHz.
• Dual mode interface also supports Intel processors.
• Interrupt driven or Polled mode operation.
Additional Protocol Support
• FEC Frame Synchronous scrambling.
• Programmable sequence detection.
Pin Compatibility to NIAGARA device
Low Power .13 u CMOS Technology
• 1.2 Volt core operation.
• 2.5 Volt I/O.
APPLICATIONS
• SONET/SDH OC48/STM-16 OC192/STM-64 DWDM transport
systems and DWDM metro networks.
• Transparent Add-Drop Multiplexing Transponder applications.
• Protocol Transparent Transport.
• IaDI to IrDI FEC transponder chip (6.2dB gain network to >8dB
gain network).
GENERAL DESCRIPTION
The AMCC Rubicon-LH device is a wide-area and metropolitan
transport device aimed at next generation applications, required
transparent mapping, and enhanced error correction capability.
The device utilizes the ITU G.709 frame and overhead structures
to enable deployment of full OTN compliant network elements.
Rubicon-LH will support two gain rates, the standard G.975 based
rate of 6.2dB (raw optical coding gain), and AMCC’s proprietary
EFEC code, rated at greater than 8dB (raw optical coding gain).
10GE-LAN MAPPING
The Rubicon-LH device supports 5 distinct methods to map
10GE-LAN into OTU-2 for transport. The first is the same manner
as supported in the Niagara; that is, the line rate will run at 7%
above the client rate with the full 10GE-LAN being mapped into an
expanded OTU-2 frame. In this mode, the line rate of the Rubicon
