Forum Post: RE: ADS7852: ADS7852
Hi Rajashekhar, Welcome to our e2e forum! The digital I/O levels listed in the table on page 3 of the ADS7852 datasheet show 3.0V as the minimum input high level, so the 2.6VOH of the TXCO may not...

I tried that as well. There is no change in the output. Is the clock pattern correct? Old uC is 8 bit and new one is 32 bit. Is that making any difference?

Hi Chase, Will the TSW14J59EVM be fully compatible with the DAC39J84EVM and DAC38RF82EVM for use with HSDC Pro ? Are there any known limitations or issues with using the TSW14J59EVM to control these...

The J59 will not work with HSDC Pro. you have to submit IP request and use vivado for control. Hardware wise there may not be 1:1 connections over the FMC connector since J59 does not route all HPIO...
