The following figure shows a sample circuit illustrating a termination technique for differential HSTL class-I (1.2V, 1.5V, or 1.8V) with unidirectional termination. In a specific circuit, all drivers and receivers must be at the same voltage level (1.2V, 1.5V, or 1.8V). They are not interchangeable (that is, HDIFF_HSTL_I_18 should only interface with HSTL_I_18).
The following figure shows a sample circuit illustrating a termination technique for differential HSTL class-I (1.2V, 1.5V, or 1.8V) with bidirectional termination. In a specific circuit, all drivers and receivers must be at the same voltage level (1.2V, 1.5V, or 1.8V). They are not interchangeable (that is, DIFF_HSTL_I_18 should only interface with DIFF_HSTL_I_18).
The following figure shows a sample circuit illustrating a termination technique for differential HSTL class-I (1.2V, 1.5V, or 1.8V) with unidirectional DCI termination. In a specific circuit, all drivers and receivers must be at the same voltage level (1.2V, 1.5V, or 1.8V). They are not interchangeable (that is, DIFF_HSTL_I_DCI should only interface with DIFF_HSTL_I_DCI). Only HP I/O banks support these DCI standards.
