Sundance Multiprocessor Technology Ltd. (Chesham, UK), a supplier of signal processing boards, has announced the release of a WiMax development system called the SMT703.
The SMT703 is built around Xilinx Virtex 5 FPGAs together with two WiMax RF transceivers and a mixed-signal front-end with dual 12-bit ADCs and dual 12-bit DACs. The Maxim transceivers mounted on the SMT703 are IEEE802.16-2004 compliant and support OFDM up to 64-QAM. They operate at 2.3 to 2.7-GHz and integrate a power amplifier driver, receive/transmit mixer, low-noise amplifier, receive/transmit filters, synthesizer, VCO, receive gain control, and transmit power control. Each RF transceiver is coupled with a mixed-signal front-end chip from Analog Devices that integrates two 12-bit ADCs (80 MSPS) and two 12-bit DACs (200 MSPS using interpolation) to provide analogue and digital conversions.
The SMT703 can be supplied with a range of LXT, FXT or SXT Virtex 5 FPGA devices. LXT devices are optimized for high-performance logic with low power serial connectivity, with the SXT devices optimized for DSP and memory-intensive applications with low-power serial connectivity. For embedded processing, high speed serial connectivity and embedded PowerPC, customers can select FXT devices.
For interfacing the SMT703 is fitted with SATA connectors and Fibre Optic modules carrying Virtex5 serial interfaces, LVDS Bus, RJ45 for gigabit Ethernet and a Rocket Serial Link (RSL) connector with 4 serial interfaces that are 3U PXI Express compliant.
