Fonctionnalités et applications

The PCA9511A is a hot swappable I2C-bus and SMBus buffer that allows I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9511A provides bidirectional buffering, keeping the backplane and card capacitances isolated.

Features:

  • Bidirectional buffer for SDA and SCL lines increases fan out and prevents SDA and SCL corruption during live board insertion and removal from multipoint backplane systems
  • Compatible with I2C-bus Standard-mode, I2C-bus Fast-mode, and SMBus standards
  • Built-in DV/Dt rise time accelerators on all SDA and SCL lines (0.6 V threshold) requires the bus pull-up voltage and supply voltage (VCC) to be the same
  • Active HIGH ENABLE input
  • Active HIGH READY open-drain output
  • High-impedance SDA and SCL pins for VCC = 0 V
  • 1 V precharge on all SDA and SCL lines
  • Supporting clock stretching and multiple master arbitration/synchronization
  • Operating power supply voltage range: 2.7 V to 5.5 V
  • 0 Hz to 400 kHz clock frequency
