Q:How many can be set for sampling clock at most in infinite transfer?

A:The value depends on the system you use, the following result reference value is based on the state which the other application isn't run.

CPU:Pentium4 2.40GHz
Distribution: RedHat Linux 9
Condition: In input infinitely transfers, transfer can process which uses internal clock and does not occur "FifoFull" error.
Result: 13.3MHz

CPU:Pentium4 2.40GHz
Distribution: RedHat Linux 9
Condition: In output infinitely transfers, transfer can process which uses internal clock and does not occur "FifoEmpty" error.
Result: 6.6MHz
