Other Parts Discussed in Thread: ADC12DL500, LMK04828, LMX2582
Tool/software:
I am designing a PCB that includes one ADC12DL500 ADC chip, using the ADC12DL3200EVM design as a reference, for use with the AC701 FPGA development board.
I will provide the ADC clock from an external source, while using the internal clocking structure of the AC701 FPGA board.
Therefore, I believe I do not need to use the LMK04828 or LMX2582 clocking ICs.
However, in the timing diagrams, I see that the SYSREF signal is typically provided by the LMK04828.
Do I need this SYSREF signal? and I'm a bit confused about how I should drive this signal externally if I want to use it.
The operating modes I plan to use, according to the timing diagrams in the ADC datasheet, are as follows:
Single or Dual Channel: LDEMUX = 0 or 1, DES_EN = 0 or 1, LALIGNED = 1
