Figure 4. Block Diagram of SERDES Usage
The power supply of the input and output buffers of the SERDES quads can be individually set to either 1.2V or
1.5V. This is done by headers J18, J20~J24. Table 15 shows the jumper settings of these headers for applying
either 1.2V or 1.5V power to the SERDES input and output buffers.
