LED Interface
Introduction
The IXF1110 MAC uses a serial interface consisting of three signals to provide LED data to
a serial-to-parallel logic external driver. The three signals are as follows:

• The IXF1110 MAC generates a start condition.
• The IXF1110 MAC sends a device address word with the Read/Write bit cleared to
• The optical module acknowledges receipt of the device address word.
• The IXF1110 MAC sends the data word address.
• The optical module acknowledges receipt of the data word address.
• The IXF1110 MAC sends the data byte to be written.
• The optical module acknowledges the data word.
