Interface module handles 1280-MB/s, full-duplex data transmission signals with bandwidths in excess of 500 MHz
Dec 7, 2004 4:38 PM 

A new module supports a sustained 1280 MB/s full-duplex interface. It is suitable for digitized signals with bandwidths in excess of 500 MHz and sampled at rates of 1 GHz, and above. Introduced by Spectrum Signal Processing, it is the TM1-3902 digital intermediate frequency (IF) interface module. It includes a reference design kit that can be used to support various multichannel architectures such as those required for direction finding and smart antenna applications.

The TM1-3902 is intended for customers who require their own custom digital IF interface between RF front-ends and Spectrum’s Software Communications Architecture-enabled SDR-3000 products.

The module can be used as a stand-alone product to provide a digital IF interface to SDR-3000 products. Developers can also connect third-party products that support a digital interface directly to the daughter sites on the TM1-3902. These sites support the digital IF interface integrated in RF solutions from Digital Receiver Technology Inc. and DRS Signal Solutions Inc.

A second function for the TM1-30902 is as a complete reference design package comprising documentation, source code, hardware pin-outs, schematics and firmware. This enables customers to create their own modules based on the digital IF interface. Test code showing full-speed operation of the interface to the SDR-3000 channelizer is supplied.

Included in the TM1-3902 is a user-programmable Xilinx Virtex-II Pro XC2VP30 field-programmable gate array that enables users to tailor the digital IF interface to their specific needs.
