Other Parts Discussed in Thread: DS100DF410, DS125BR800

Hello,

My customer has some questions about DS100DF410.

[Background]

DS100DF410 is SMBus device.

Operating Frequency of SMBus is 10kHz to 100kHz.(Refer to SMBus Specification ver1.1 or ver 2.0)

But SMBus clock rate of DS100DF410 is 10kHz to 400kHz.

[Q1] Is SMBus clock rate Specification of DS100DF410 right? (Is maximum SMBus clock rate 400kHz? or 100kHz?)

[Q2]What should the timing specifications of DS100DF410 refer to ?

      (SMBus Specification ver1.1? or SMBus Specification ver2.0? or I2C Specification ver2.1?)

      * Timing specifications are for example TBUF, THD:STA, TS:STA, ・・・.

 

Regards,
