Broadcom Announces BCM8155 and BCM8157, New 10G PHY Transceivers for 65nm Process Technology
Broadcom Introduces Low Power 10G Physical Layer Device for Long Haul and Metro Transmission in Optical Transport Networks
Next Generation Integrated, Cost Effective, Multi-Rate Transceivers Support 8.5 Gbps to 11.352 Gbps while Achieving Greater than 50 Percent Savings in Power Consumption
Broadcom Corporation (Nasdaq:BRCM – News), a global leader in semiconductors for wired and wireless communications, today announced that it is expanding its long haul transmission chip portfolio with new 10 Gigabit (10G) physical layer (PHY) transceivers designed in 65 nanometer (65nm) process technology. The Broadcom® BCM8155 and BCM8157 multi-rate transceivers support data rates ranging from 8.5 Gigabits per second (Gbps) to 11.352 Gbps and feature the industry’s lowest power consumption with industry-leading long reach jitter performance. The BCM8155 provides additional support for Return to Zero (RZ) modulation. These next generation Broadcom PHYs are both fully integrated, multi source agreement (MSA)-compliant devices that support multi-rate applications including 8.5G Fibre Channel, OC-192 SONET/SDH, 10 Gigabit Ethernet (10GbE), 10G Fibre Channel (10FC) and optical transport networks (OTNs)/OTU-2 data rates.
Highlights/Key Facts:
- SONET/SDH and OTN equipment is required for long haul transmission and the most cost effective and widely deployed modulation in use today are the Non Return to Zero (NRZ) and Duo-binary (DB) formats. RZ modulation is more suitable for longer transmission distances because it is not adversely affected by fiber dispersion, however, it has not been widely deployed due to its higher cost and power consumption. Existing solutions in the market today require two-chips—a mux and an NRZ to RZ converter—that consume as much as 2.5 watts of power.
- Broadcom’s expertise in 65nm design has made it possible to integrate the RZ modulation format into a cost effective device that consumes only 600 milliwatts (mW), or 50% less power than competing two-chip solutions, making the BCM8155 10G PHY ideally suited for OTN equipment that uses 300-pin MSA-compliant modules for long haul transmission.
- The BCM8155 and BCM8157:
-
- Are fully integrated MSA-compliant, multi-rate SONET/SDH, 10GbE, 10FC and OTU-2 optical transport network transceivers that operate at 8.5GFC (8.5Gbps), OC-192 (9.953 Gbps), 10GbE (10.3125 Gbps), 10FC (10.513 Gbps) or FEC data rates (i.e. 10.664/10.709/11.096/11.318/11.352 Gbps).
- Support NRZ and DB modulation.
- Provide industry-leading low jitter generation of less than 200 femtoseconds (or 2mUI RMS) and provide ample margin for designs required to meet the International Telecommunication Union (ITU) and Telcordia® maximum specification limit of 10mUI RMS for jitter generation.
- The BCM8155 incorporates additional advanced features such as RZ modulation, duo-binary encoder, dispersion compensation, 10GHz clock output, 10G transmit pre-emphasis and pseudo random binary sequence (PRBS) pattern generation and detection capabilities.
- The BCM8157 is targeted for use in line cards that interface to XFP modules in metro applications.
