multi_ddc_IPcore.rar (1.99 MB) 全新架构高性能/高性价比64 channel DDC IP核研发成功
主要创新点:
32-Channel DDC 64-Channel DDC可集成到单片300万等效逻辑门的Xilinx或Altera FPGA中,功耗2.5~3W
有需要的可以联系QQ:39650917,email:pornanier@163.com
还可根据客户的不同带宽等特定需求定制通道数(4/8/16/32/64通道)

技术指标(64通道核):
• Two 16-bits ADC inputs, Fs > 220MS/s
• 64 independently configurable channels
• Independent tuning, gain, sample rate and output filter selection controls
• Output sample rates from Fs/128 to Fs/8192 or more
• Maximum alias-free output bandwidth of Fs/320 (= 625kHz for Fs = 200MS/s)
• 8 programmable output shaping filters
• Example filter performance: 0.1dB peak to peak ripple, alias-free bandwidth 80% of output sample rate and 90dB
image rejection
• Centre frequency tuning accuracy to within 0.012Hz(Fs/2^34)
• Resampling provides any output rate to within 0.012Hz(Fs/2^34)
• >90dB spurious free end to end performance
• Resampled output maintains >90dB spurious free performance
• 0 to 90dB gain boost MGC & AGC


应用xilinx的V6,输入采样率可达350MSPS,32通道版本可以满足TD-SCDMA系统的带宽要求(最大抗混叠带宽为Fs/160)
