Other Parts Discussed in Thread: LMK04828,
Hello,
I'm developing a custom FPGA board (with a Kintex 7) that communicates with the ADS42JB69EVM board and ADC using the FMC connector. I'm going to use the LMK04828 included in the board to generate all the external clocks but I'm having difficulties understanding the configuration of this chip.
Summarizing my clocks/rates are (using JESD204B Xilinx LogiCORE IP core for the FPGA):
-Line rate = 2.5 GHz
-ADC Clock / Refclck = 250MHz
-GLBLCLK = Line rate / 40 = 62.5 MHz
-Sysref = 6.25 MHz
My main question is which frequency do I have in the CLKIN0, CLKIN1 and CLKIN2 inputs (can't find this one in the schematic)?
Thanks,
Gerard
