Info Content
Keywords I2C-bus, 2-wire bus, twisted pair cables, LED lighting, communication
cables, Cat5e, Cat6, Fast-mode, Fast-mode Plus, Fm+, inter-IC, SDA,
SCL, PCA9605, RS-485, CAN bus
Abstract The availability of powerful I2C buffers that drive their I/Os on both sides to
a nominal ground or ‘zero offset’ logic level allows the removal of noise
introduced into one section of a larger bus system. That ‘regeneration’ of
clean I2C signal……
