There is an Excel calculator which makes it easy to determine the maximum I
speed when using the PCA9601. The calculator and instructions can be found at
www.nxp.com/clockspeedcalculator.
PCA9601
The actual LOW period will be 407 + 126 = 533 ns, which exceeds the minimum Fm+
500 ns requirement. This system requires the bus LOW period, and therefore cycle
time, to be increased by 33 ns so the system must run slightly below the 1 MHz limit.
The possible maximum speed has a cycle period of 1033 ns or 968 kHz.
