你好,第一次用ADC32J4X,我只使用了通道A,请问SYNCM~,SYNCP~和SYSREFM,SYSREFP这两组信号是否是必须的?
Kailyn Chen:
个人认为是需要的,因为这里的sync信号主要用于时钟信号同步的。
An external SYSREF (subclass 1) or SYNC~ (subclass 2) signal is used to align all internal clock phases and the local multiframe clock to a specific sampling clock edge. This process allows synchronization of multiple devices in a system and minimizes timing and alignment uncertainty.

那ADC采集的到数据传输给FPGA的话,SYNC~信号由FPGA提供吗?SYSREF信号是不是由什么提供?
