SMBus Digital Switching Characteristics
Unless otherwise noted, these specifications apply for V
80 pF. Boldface limits apply for T
switching 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 (Note 13)
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.
Stop Condition SMBCLK High to SMBDAT
Low (Stop Condition Setup)
SMBus Repeated Start-Condition Setup Time,
SMBCLK High to SMBDAT Low
