TDC7201-ZAX-EVM: How to connect FPGA and TDC7201

Hello, dear engineer, I am trying to drive TDC7201 with FPGA. I wrote the program according to the few TDC7200 routines, but when I connected TDC and FPGA, I couldn't drive it and there was no response. I connected ENABLE, SCLK, GND, INTB1, VDD, CSB1, DOUT1, DIN. I made sure that I should choose mode 1 of TDC1, and I didn't connect them wrong. That blog can also drive it, because I have successfully driven it with MSP myself. When connecting with MSP, EXT_CLOCK was not connected, so I didn't connect CLOCK. I would like to ask if the driving failure is due to this reason. If not, I would like to hear your thoughts.The blog address is blog.csdn.net/…/121719751

您好，

     既然您已用MSP板成功驱动了，FPGA直接复制其相关接口即可。

     在用户手册18页有与MSP接口的定义。

     tdc7201芯片的CLOCK脚需要时钟输入。

     对于TDC7201-ZAX-EVM可以使能“OSC_ENABLE” 来使用板载时钟。
