Broadcom Announces 10 Gigabit Optical Transceiver for High Speed SONET/SDH, 10 Gigabit Ethernet and Fibre Channel Networks

New Third Generation, Single-Chip, Multi-Rate Transceiver Allows Network Equipment Manufacturers to Build Low Cost, Compact Modules and High Density Line Cards

LAS VEGAS, NetWorld+Interop 2004, May 11, 2004 /PRNewswire-FirstCall via COMTEX/ -- Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, today announced a low power, multi-rate serial 10 Gigabit transceiver (transmitter/receiver) that enables networking equipment manufacturers to standardize on a single chip design supporting both Very Short Reach (VSR) and Long Reach (LR) optical link applications. Broadcom's new transceiver is especially suited for LR applications, providing peak performance and a small footprint for compact module and high-density line card solutions.

The Broadcom® BCM8152 multi-rate Gigabit transceiver is targeted for both module and line card applications. For module applications, the low jitter generation and ability to adjust the phase and threshold of input signals allow an optical module to achieve longer reach. For line card system applications, high port density within a small footprint is achieved. For this application, a special 10 Gigabit serial receiver is designed to improve the eye opening of the received signal in support of the 10 Gigabit small form factor interface (XFI) as specified by the 10 Gigabit Small Form Factor Pluggable (XFP) Group.

Modules and high-density line cards take electrical signals and convert them to serial optical signals for transmitting and receiving data throughout an optical network (which is the preferred method used to transmit data at high speeds over long distances). The BCM8152's small form factor is designed to reside within 10 Gigabit hot-pluggable modules and high-density line cards for optical switches and routers within metropolitan area networks (MANs), multi-service switching platforms, add and drop multiplexers (ADMs) and Dense Wave Division Multiplexing (DWDM) transport equipment.

According to Dell'Oro Group's "4Q 2003 Router Summary Report," there is an increase in demand for both 10G POS (Packet over SONET/SDH - Synchronous Optical Network/Synchronous Digital Hierarchy) ports and 10 Gigabit Ethernet (GbE) ports, and it is expected that 10 Gigabit per second (Gbps) router revenue will grow 31% year-over-year in 2004. SONET and SDH are networking standards for transmitting data at high rates over fiber optic lines.

The BCM8152 is a fully integrated, Multi Source Agreement (MSA) compatible, multi-rate transceiver that operates at high speed transmission rates supporting OC-192/STM-64 (9.953 Gigabits per second), 10 Gigabit Ethernet (10.3125 Gbps), 10 Gigabit Fibre Channel (10.519 Gbps) or one of the supported forward error correction (FEC) rates (10.664, 10.709, 11.095 and 11.318 Gbps). With low jitter generation of 200 femtoseconds (or 2mUI RMS), the BCM8152 provides ample margin for designs required to meet the ITU and Telcordia maximum limit of 10mUI RMS for jitter generation.

"For wideband tunable 300-Pin MSA transponders to address long haul applications, low jitter and the ability to adjust the phase and threshold for control are required when providing this type of high-quality and reliable transponder," said Jerry B. Wood, Director of Harris Corporation, Government Communication Systems Divisions. "The BCM8152 met our performance requirements the best and is targeted to address the needs of long reach and long haul applications."

"The BCM8152 is a third generation 10 Gigabit optical transceiver that sets new levels of flexibility and performance in a single chip, CMOS device. Broadcom has continued to invest in transceiver development to enable the transition of networking equipment to 10 Gigabit data transmission by continuing to offer high performance, cost-effective solutions," said Nariman Yousefi, Vice President and General Manager of Broadcom's Networking Physical Layer/Optical Line of Business.

BCM8152 Technical Information

The BCM8152 transceiver offers a high level of silicon integration including a 16:1 multiplexer, 1:16 demultiplexer, clock multiplier unit, and clock and data recovery unit with a limiting amplifier. Low cost is achieved through the use of a standard CMOS process and a small 15 x 15 mm plastic BGA package.

Price and Availability

Samples of the BCM8152 are currently available to all Broadcom customers. Production is scheduled for July 2004 with large volume pricing at $91 each.

Reference designs for BCM8152 XFP applications are also available to accelerate time-to-market for low-cost line card and interconnect solutions based on the XFP module specification. The XFP reference design includes an evaluation board, reference schematics, a user manual, and software with a graphical user interface (GUI). A standard BCM8152 evaluation board is also available for customer evaluation.
