10G DWDM TRANSPORT PROCESSOR
PRODUCT
Brief
BCM8511
•Single-chip 10G DWDM transport processor integrates
9.953/10.664/10.709 Gbps transceiver, G.709 Digital
Wrapper (DW), (v8.3, 10/9/2000), G.975 Forward
Error Correction (FEC), RS(255,239), and
SONET/SDH performance monitor (PM).
•Flexible data interface options. Both input and output
are independently programmable as 10G serial data or
16-bit parallel clock and data.
•Flexible modes of operation include DW with FEC,
optional SONET/SDH PM, DW without FEC, optional
SONET/SDH PM, SONET/SDH PM, bypass DW and
FEC, and pass-through modes.
•Utilizes a power-efficient design with the unused blocks
powered down.
•Performs frame and byte alignment on received OTU2
frames.
•Monitors for Out-of-Frame (OOF) condition on OTU2
frames.
•Monitors section, path, and tandem connection on the
OTU2 frames.
•Scrambles and unscrambles OTU2 frames.
•Optionally inserts overhead bytes into transmitted
OTU2 frames.
•Performs RS(255,239) FEC decoding/encoding
functions.
•Monitors OTU2 frame for FEC statistics: total
corrected bits, corrected bytes, and uncorrectable
blocks per second.
•Performs frame and byte alignment on received
SONET/SDH frames.
•Monitors and reports OOF, Loss-of-Signal (LOS), and
Loss-of-Frame (LOF) conditions on SONET/SDH
frames
•Scrambles and unscrambles SONET/SDH frames.
•Monitors and reports section trace messages (J0 byte)
conditions.
•Monitors B1/B2 bytes and reports parity error on
SONET/SDH frames.
•Extracts and optionally inserts section and line
overhead bytes of SONET/SDH frames.
•Monitors and reports Signal Degrade (SD) and Signal
Fail (SF) conditions on SONET/SDH frames.
•Monitors K1/K2 bytes to report Automatic Protection
Switch (APS), Alarm Indication Signal (AIS), and
Remote Defect Indication (RDI) conditions on
SONET/SDH frames.
•Extracts and optionally inserts Data Communication
Channel (DCC) bytes (D1–D12) via the serial I/O.
•Extracts and optionally inserts section and line
overhead bytes via the serial I/O.
•Monitors the S1 byte for mismatch and inconsistent
values.
•Monitors the M1 byte and reports Remote Error
Indication (REI) conditions on SONET/SDH frames.
•Inserts AIS conditions on SONET/SDH frames.
•Generates and inserts B1/B2 bytes on SONET/SDH
frames.
•Extracts and optionally inserts General
Communications Channel (GCC) bytes via the serial
I/O or microprocessor.
•Extracts and optionally inserts OTU2 overhead bytes
via the serial I/O or microprocessor.
•Provides a standard IEEE 1149.1 JTAG test port for
boundary scan.
•Provides microprocessor interface for control register
access as well as overhead insertion and extraction
BCM8511 FEATURES (CONT.)

•Compact low profile package: 31 x 31 mm, HSBGA
•Standard 0.18 mm CMOS process
The BCM8511 is a single-chip 10G DWDM transport
processor that supports the following major functions on a
DWDM line card:
• Integrated 9.953/10.664/10.709 Gbps transceiver
• G.709 Digital Wrapper (DW) (v8.3, 10/9/2000)
• G.975 Forward Error Correction (FEC), RS(255,239)
• SONET/SDH performance monitor (PM)
The device includes flexible data interface options. Both data
inputs and outputs are independently programmable as 10G
serial data or 16-bit (LVDS) parallel clock and data. The
BCM8511 also has flexible modes of operation:
• Digital wrapper with FEC
• Optional SONET/SDH PM digital wrapper without FEC
• Optional SONET/SDH PM
• SONET/SDH PM with digital wrapper and FEC bypassed
The integrated transceiver performs the clock and data recovery
(CDR) and the demultiplexing functions on the serial input
data. It performs the clock multiplication (CMU) and the
multiplexing functions to produce the serial output data. The
transceiver is data-rate programmable in order to support the
OC-192 SONET/SDH rate (9.953G), the G.975 FEC rate
(10.664G), and the new G.709 FEC rate (10.709G).
The BCM8511 performs digital wrapper frame and byte
alignment, overhead extraction, and performance monitoring
on the input data. FEC and correction statistics are performed
on the frame and byte aligned digital wrapper frames.
SONET/SDH section and line overhead byte
extraction/insertion and performance monitoring are performed
on the FEC-corrected data.
All necessary performance monitor functions for SONET/SDH
section and line overhead bytes are provided for Operations,
Administration, Maintenance, and Provisioning (OAM&P).
These functions include error checking, overhead data
extraction, and insertion. Detected errors and accumulated error
counts are accessible through a microprocessor port.
Optionally, digital wrapper overhead bytes can be inserted into
the data stream. Processed frames are FEC-encoded and
serialized in the transceiver.
Applications:
• DWDM transmission equipment
• Repeaters, add/drop multiplexers, and cross-connects
• Fiber optic terminators and test equipment
