Hello there,
We are checking the above isolated current shunt and voltage measurement reference design based on AMC1304M05 and AMC1304M25 and we have the following doubts:
1. The design employs an external PLL to generate the clock for the modulators. Is it possible to use the MCU PWM output to perform such clock?
2. The schematic shows that the device is a AMC1304M05/25 using signals CLKIN and CLKIN_N / DOUT and DOUT_N. Nevertheless, the IC datasheet shows these M versions (CMOS) does not have CLKIN_N and DOUT_N pins, rather the L versions (LVDS). So, what is the correct version of the IC employed?
3. What is the main difference between these devices and the AMC1305 family?
Thank you in advance.
Bests,
Douglas
