I am Trying to measure the delay of 1PPS Signals of two Rb clock, and to measure the delay I want to use some ICs based TDC/TIC with smallest size possible like TDC7200. But the problem is that delays are in ms say 500ms to 700ms and the TDC/TIC which I have, has only measuring range up to 10ms.
So to overcome this problem there are two solutions which I can think of:
1.) Either I reduce this delay by some means and bring it to few ms, which right now, I don't know How can I do that because Delay is a constant quantity which cannot be changed.
2.) or I should use the TDC/TIC with higher measuring range, but to do this, I will have to switch from ICs based TDC/TIC to some big devices like Keysight-53230A, and I don't want to use this huge device.
Please suggest me some ideas to solve this problem.
PS: Reducing delay by some means will be a great help for me as I already have some TDC/TIC ICs for that.
PPS: Someone suggested me TAPR-TICC, which is a great device, but its size is equal to the Arduino-Mega, which is an issue for me.
