LвЂ‰DESIGN FEATURES Low Offset 2-Wire Bus Buffer Provides
Capacitance Buffering, Stuck Bus
Recovery, and Tolerates High VOL by John Ziegler Introduction
High availability computing, networking and data storage systems employ
system management buses such as I2C
or SMBus to monitor system health.
These simple serial buses allow system controllers to monitor parameters
such as temperature and voltage,
read vital product information from
individual cards, and make changes
to the system, such as controlling fan
speed. As these systems increase in
complexity, several implementation
issues arise with the system management bus.
First, each additional device on the
bus adds a capacitive load. The bus
capacitance of a large system makes
meeting rise time specifications very
difficult. While a strong pull-up resistor
can reduce the rise time, the penalty
is increased VOL and decreased noise
margin. Second, some devices that can
communicate via I2C or SMBus have a …
