SoC chip for 4G/LTE microwave backhaul achieves 1.25Gbps speed

Broadcom Corporation has announced its latest innovation for 4G/LTE microwave backhaul, the BCM85620 system-on-a-chip (SoC) for higher bandwidth in mobile backhaul. The BCM85620 is designed to deliver Gigabit bandwidth by combining a baseband modem and network processor in one chip.

The BCM85620 combines the functionality of up to ten off-the-shelf application-specific standard parts (ASSPs) into one SoC, dramatically lowering power consumption and system costs, says Broadcom.
Key facts of BCM85620 as listed by Broadcom include:
Industry's highest capacity (1024QAM modulation) delivers Gigabit and beyond performance
Packet fragmentation and header compression combined with ACM-aware traffic management enables radio-optimized networking
Robust Adaptive code and modulation (ACM) technology automatically provisions bandwidth
Extreme phase noise tolerance reduces system cost and improves spectral efficiency/system gain
Synchronization over packet network - SyncE and 1588 support over ACM and protection switching
Low latency for 4G networks
Integrated carrier grade network processor

Broadcom says the BCM85620 provides radio-optimized traffic delivery, including robust clock delivery over packet transport needed for network synchronization with enhanced radio performance and advanced networking capabilities and coupled with 1.25Gbps throughput and 25 percent higher capacity than existing solutions, enables wireless backhaul systems to support the demanding requirements of 4G/LTE networks.

Market Drivers as per Broadcom:
Global mobile backhaul expenditures are expected to reach $8B billion by 2014
Ethernet is expected to be the dominant carrier technology by 2014 in mobile backhaul
Microwave backhaul is the most prevalent technology used in the global mobile backhaul market with >55 percent of all backhaul connections

Availability: The BCM85620 is now available.
