The following figure shows a sample circuit illustrating a unidirectional board topology for POD (1.0V or 1.2V) with matched driver and receiver termination values. Only HP I/O banks support these standards.
Figure 1. POD with Unidirectional Signaling
The following figure shows a sample circuit illustrating a termination technique for POD (1.0V or 1.2V) with bidirectional termination and matched driver and receiver termination values. In a specific circuit, all drivers and receivers must be at the same voltage level (1.0V or 1.2V); they are not interchangeable (that is, POD12 should only interface with POD12).
