Lattice semiconductor introduces multi-gigabit baseband processor for wireless fiber applications


New SB6541 Combined with RF Transceivers Built on SiBEAM™ Technology Deliver Multi-Gigabit Speeds in the 60 GHz Frequency Band


  • SB6541, combined with Lattice’s Sil6340 and SiI6342 RF transceivers, offers industry’s first comprehensive solution for wireless access and backhaul markets
  • High throughput architecture supports high sustained data rates required by advanced mobile and wireless access networks
  • Beam-steering technology on phased array antennas reduces installation and maintenance costs in point-to-point networks and enables next-generation mesh networks

Lattice Semiconductor Corporation (NASDAQ: LSCC), the leading provider of customizable smart connectivity solutions, today announced availability of the company’s new baseband processor. The SB6541 is designed for use in conjunction with Lattice’s Sil6340 and SiI6342 RF transceivers to target fixed wireless access and wireless backhaul of urban broadband infrastructure such as LTE small cells and metro Wi-Fi access points.

Increasing demand for gigabit IP data to the home is driving demand for fixed wireless broadband access. In addition, in high data density areas, gigabit IP data connectivity is required for metro Wi-Fi and LTE deployments. The 60 GHz band is ideal for these applications due to the large bandwidth available and the unique propagation characteristics of the band that allow high spectrum reuse, both of which are essential for next-generation wireless network architectures. The chipsets offer the industry’s first complete solution in the 60 GHz frequency band, leveraging SiBEAM™ technology for increased data throughput and network reliability.

Lattice’s chipsets also support beam-steering technology on phased array antennas. Devices that implement beam-steering require only rough alignment and can be installed quickly without specialized skills. A link can then be established between that node and other nodes in the network without manual intervention, and maintained even under changing environmental conditions or network reorganization. This significantly reduces installation and maintenance costs.

“Our connected world is now ‘wireless first’,” said Khurram Sheikh, chief strategy and technology officer at Lattice Semiconductor. “Data demand on wireless networks exceeds the ability of existing infrastructure to keep pace with user demand. With the availability of our SB6541 baseband processor, combined with our RF transceivers, OEMs and service providers can now build infrastructure hardware that leverages the advantages of the 60 GHz frequency band to deliver network throughput capacities of up to 2 Gbps.”

When used in combination with the Lattice Sil6342 RF transceiver, the SB6541 supports Internet Protocol (IP) data rates of up to 2 Gbps, with a typical throughput of 1 Gbps at a range of up to 300 meters.  The device integrates with the RF transceiver via high-speed analog I/O and a digital control interface. The SB6541 processor can be easily integrated into any system design through a PCIe interface.
