This Figure shows a sample circuit illustrating a unidirectional termination technique for SSTL18, SSTL15, SSTL135, or SSTL12. In a specific circuit, all drivers and receivers must be at the same voltage level (1.8V, 1.5V, 1.35V, or 1.2V); they are not interchangeable (i.e., SSTL12 should only interface with SSTL12).

This Figure shows a sample circuit illustrating a bidirectional termination technique for SSTL18, SSTL15, SSTL135, or SSTL12 with DCI. In a specific circuit, all drivers and receivers must be at the same voltage level (1.8V, 1.5V, 1.35V, or 1.2V); they are not interchangeable (i.e., SSTL12_DCI should only interface with SSTL2_DCI). DCI standards are only supported in HP I/O banks.
