Num
Data in Typical column was characterized at 5.0 V, 25 °C or is typical recommended value.
When ICS is configured for FEE or FBE mode, input clock source must be divisible using RDIV to within the range of 31.25 kHz
to 39.0625 kHz.
This parameter is characterized and not tested on each device.
Proper PC board layout procedures must be followed to achieve specifications.
