Hello to all,
I would like to clock the ADS5282EVM board using the CDCE62005 clock generator provided by TI.
At the moment i succesfully digitize a sine wave, using a HP clock generator which provides to the ADS5282EVM board a 10MHz clock input.
I would like to clock the ADC using higher frequencies in order to achieve the full sampling rate (60Msps) of the ADC. Thus i chose to use the CDCE62005EVM.
i am using the crystal oscillator provided in the board as a refernece frequency. The ADC works pretty well for a 10MHz frequency provided by the CDCE using a LVCMOS output signal without termination.
the problem is that it not works for higher frequencies...
i would like to ask if i should provide some other reference frequency in the CDCE?
Or the problem may rely on the vhdl code that deserialize data from the ADC to my FPGA board?
In what way should i use the CDCE to provide clocks (20MHz,30MHz,40Mhz,50MHz,60MHz) to the ADC without using external reference from function generators.
I bought this board as a cheap solution for clocking the ADC at higher frequencies than 10MHz because my HP generator provides a maximum frequency of only 10 MHz.
