Dual-channel DDS Coherent Signal Source with Arbitrary Phase

Synchronizing signal is very important in communication system.Once signal can′t be synchronized rigidly,bit error rate may rise,or even system breaks down.Single channel source can no longer meet the development of communication technology and it is necessary to study coherent signal source with arbitrary phase difference based on multi-DSP.Adopting Sunplus SPCE061A as control core in the design,which accurately controls two chips of DSP(AD9850 and AD9851) to gene-rate two-way signal source with arbitrary phase difference,and successfully implements a design of special signal source,which keeps phase quadrature synchronization with dual-DSP synthesizer.
