Other Parts Discussed in Thread: UCD90124A
My customer want to use sequencer and they want to know something about Clock/data rise time and fall time(tr and tf).
UCD90160A DATASHEET: max Tr is 120ns
UCD90124A DATASHEET: max Tr is 300ns
SMBUS Protocol: max Tr is 1000ns@ 100kHz, 300ns@ 400kHz , 120ns@ 1MHz
Customer want to know:
1 Why our UCD90160A and UCD90124A have different tr spec? And why their spec both different with SMBUS Protocol?
2 Can they use I2C whose 300ns>tr>120ns in UCD90160A? What about 1000ns>tr>300ns?
If not, what will happen if they use like this?
