Serial Bus Buffers, Extenders, and Accelerators
The Analog Devices family of I2C solutions support hot swappable, 2-wire bidirectional bus buffers to allow I/O card insertion into a live backplane without corruption of the data and clock busses. Additional supported 2-wire buses include SMBus, PMBus, the ATCA intelligent platform management bus (IPMB), and the HDMI DDC bus. I2C/SMBus Accelerators improve bus transitions to allows multiple device connections or a longer, more capacitive interconnect, without compromising slew rates or bus performance. ADI's software-programmable and pin-selectable I2C multiplexers help resolve I2C address limitations, increase fan-in or fan-out, and integrate bus buffers and rise time accelerators for an all-in-one solution. Resistor configurable I2C address translators can be configured with over 100 unique slave addresses to allow multiple slave devices with the same address to coexist on the same bus.
