Tundra Semiconductor Corp. has released the Tsi620, a multi-standard serial RapidIO switch that lowers 3G baseband costs by bridging RapidIO-based DSP clusters to low cost embedded embedded processors and FPGAs.

The device lowers 3G baseband processing costs by directly connecting a switched cluster of RapidIO-enabled DSPs to low cost PCI-enabled microprocessors, in many cases leveraging investment in existing software solutions. Further cost savings are realized by taking advantage of the Tsi620's unique RapidIO port for FPGA interconnect. This port allows baseband designers to select cost competitive FPGAs without integrated SerDes.

The Tsi620 features RapidIO interface of up to three ports in 4x mode or six ports in 1x mode; and 1.25, 2.5 and 3.5Gbaud data rate as well as non-standard speeds in between. Non-serial FPGA interface supports RapidIO (layers 2 and 3) at 1- to 10Gbps data rate. Also, the device's PCI interface operates up to 66MHz and supports up to four devices.

In addition, the Tsi620 offers low latency with cut-through capability, enhanced SerDes for low power solution and high-performance multicast engine. The switch also leverages Tsi57x technology at 120-to 200mW per RapidIO port with typical power of less than 4W.

"Baseband cards can be implemented with significant cost savings with the Tsi620, while at the same time benefiting from the latest signal processing capacity of today's high performance multi-core DSPs," said Daniel Hoste, CEO, Tundra. "This new RapidIO Switch allows customers to both increase their baseband performance and significantly reduce overall system cost," continued Hoste.

The Tsi620 comes in 27mm x 27mm 675-pin PBGA eutectic and RoHS packages in industrial and commercial temperature operating ranges.
