IMX3112
I3C Basic 1:2 Bus Multiplexer Description Features The IMX3112 is a dual bidirectional 1:2 translating
multiplexer for I3C/I²C bus. The input HSDA/HSCL
pair can fan out to two output pairs (or channels),
either individual output channel can be selected. • 1:2 bus multiplexer • Two-wire programmable I²C or I3C bus serial
interface • Single device load on the Host bus • Up to 12.5MHz transfer rate • Single 1.8V power supply input • 1.0V VLDO output at VIO pin • Supports 1.0V, 1.1V, and 1.2V Push-Pull IO
levels • Supports 1.0V, 1.1V, 1.2V, 1.8V, 2.5V, and 3.3V
open-drain IO levels • Integrated Temperature Sensor; 0.5°C accuracy
with 0.25°C resolution • Packet Error Check (PEC) function • Parity Error Check function • Bus reset function • In-band Interrupt (IBI) • Up to 8 unique addressing • Programmable I²C, I3C bus addressing scheme • 9-pin thermally enhanced DFN package • Temperature: Industrial range of -40 °C to 125°C Applications with slave devices that share the same
address can use this multiplexer to prevent slave
address conflicts. By selecting the proper output
channel, the I3C/I²C master can access a large
number of devices across both ports. Figure 1. Block Diagram Applications Feb.27.20 • Pin reduction in host or ASIC or platform
controllers • Server boards • PCs/notebooks • Embedded automation Page 1 IMPORTANT NOTICE AND DISCLAIMER
