design features Bus Buffers Simplify Design of Large, Noisy I2C Systems
Rajesh Venugopal The original I2C specification limited the
maximum bus operating frequency to
100k Hz; it is now 400k Hz . As systems grew
larger, bus buffers were introduced to
buffer bus capacitance and solve several other common I2C issues. Early bus buffers degraded certain I2C specifications
in a manner that can be unacceptable
in large noisy systems. The LTC4313 and
LTC4315 family of bus buffers offers the
benefits of traditional bus buffers while
maintaining compliance to all I2C voltage DRIVER HIGH
0.9 VCC
0.7 VCC
VOLTAGE The I2C bus and its derivativesвЂ”such as SMBus, PMBus,
the DDC bus of HDMI and IPMB bus of ATCAвЂ”are used in
a variety of large systems to transfer vital system information.
These bus specifications have gained wide acceptance
due to ease of use. The I2C bus is a digital serial 2-wire
bus consisting of a single clock (SCL) and single data
(SDA) line. The I2C protocol employs open drain pull-downs
to drive the bus low, and resistors or current sources to
pull the bus high. The maximum allowed pull-up current
and bus capacitance are 4mA and 400pF, respectively. LOGIC HIGH …
