I²C repeaters

Our NCA9xxx family of I²C repeaters offers a reliable solution for boosting system performance by preserving signal quality, extending bus range, and supporting the increasing demands of interconnected and intelligent enterprise systems. I²C repeaters provide a low-power option, consuming ultra-low power in standby and disabled modes, making them ideal for power-sensitive applications. These repeaters are crucial for expanding and enhancing bus signal load capacity, avoiding an overload capacitance.  I²C bus systems can be easily extended without compromising performance during switching, even in complex systems spread over longer distances.

Key Features

 

  • Dual channel bidirectional I²C bus repeater 
  • Voltage level translation from 1.08 V to 3.6 V at both port A and port B
  • Guaranteed 1 MHz operation (true I²C  FM+) and supports FM and SM operations
  • No static voltage offset
  •  Schmitt trigger inputs improve the noise immunity by filtering the noise components of the signals
  • Input and output rising-edge signal accelerators at all I/O’s
  • Lock-free operation
  • Glitch-free and sequence-independent IC power-up
  • I²C clock-stretching support
  • Open-drain input/outputs
  • Compatibility with I²C bus and SMBus protocols

Applications

 

  • Devices for IoT applications
  • Cell phones, tablets, laptops
  • Portable medical devices,
  • Portable instrumentation and test equipment's
  • Telecom switching and networking equipment
  • Products with many I²C slave devices and / or long PCB trace
  • Power-sensitive applications
