CINRAD C-band design based on Altera CPLD and LVDS technology

Building on its NEXRAD (Next Radar) heritage, CINRAD (Chinese Next Generation Radar) incorporates many technological advances to further enhance performance, reliability and can be easily upgraded. These include an open system workstation platforms, VLSI DSP signal processor, network communications, real-time display, fibre-optical transfer, and new scan modes. The CINRAD signal processor hardware contains two major subassemblies: hardwired signal processor (HSP) and programmable signal processor (PSP). CINRAD HSP, based on Altera CPLD and LVDS technology, is the central of CNRAD system timing and control. It also receives data from receiver and transfers it to PSP in high speed. Because of the long distance between HSP and PSP, the LVDS technology has to been used.
