Note 1: All timing AC electrical characteristics and timing specifications are guaranteed by design and not production tested.
Note 2: The VCXO tracks the input clock frequency by ±60ppm.
Note 3: A master device must provide a hold time of at least 300ns for the SDA signal to bridge the undefined regions of SCL’s
falling edge.
Note 4: CB = total capacitance of one bus line in pF. Tested with CB = 400pF.
Note 5: Input filters on SDA and SCL suppress noise spikes less than 50ns.
