SMBus Digital Switching Characteristics
Unless otherwise noted, these specifications apply for V
pF. Boldface limits apply for T
characteristics of the LM63 fully meet or exceed the published specifications of the SMBus version 2.0. The following parameters
are the timing relationships between SMBCLK and SMBDAT signals related to the LM63. They adhere to, but are not necessarily
the same as the SMBus bus specifications.
SMBus Clock Frequency
SMBus Clock Low Time
SMBus Clock High Time
SMBus Rise Time
SMBus Fall Time
Output Fall Time
SMBData and SMBCLK Time Low for Reset of
Serial Interface See
Data In Setup Time to SMBCLK High
Data Out Hold Time after SMBCLK Low
Hold Time after (Repeated) Start Condition. After
this period the first clock is generated.
