目前使用ADC12DJ5200RF,采样率为10GHz,与Xilinx的KU系列FPGA互联。
由于要实现确定性延时,需要获得sysref到内部LMFC上升沿之间的延时参数,以便计算准确的延时范围。
但是文档中未提及该参数。
美国的工程师的回复:
The Ttx and Tadc parameters are in section 6.10, this gives the delay values.
These values will obviously have some variations, so the elastic buffer should include a margin to absorb the changes.
