Hello,
I develop a custom board with the LS1046A CPU.
I am using oscillator for DIFF_SYCLK and SerDes clocks.
Your specification for the clocks frequencies is not clear for me.
You specify a frequency of 100MHz with no minimum neither maximum except frequency tolerance of +/- 300ppm.
What does this mean?
Can I use any clock frequency as long as this clock is within +/-300ppm?
Is there any requirement on the clock frequency?
Can I use 25, 50, 125MHz, 156.25MHz for DIFF_SYCLK and SerDes clocks?
Thank you
Please treat tolerance of +/- 300ppm as allowed clock range specification. So minimum DIFF_SYCLK frequency is 100MHz - 300ppm, maximum frequency is 100MHz +300ppm.
Regards,
Bulat
