Product Number: ADUCM3029
What are the requirements for GPIO clock in (SYS_CLKIN)? The datasheet and hardware reference does not mention any relevant information; for example,
- Should it be AC coupled or DC coupled?
- Should it be biased?
- What are the high and low levels?
- What is the maximum and minimum input frequency?
- Are there any other limitations?
Similarly what are the characteristics of SYS_CLKOUT?
