Differential HSTL class-I pairs complementary single-ended HSTL_I type drivers with a differential receiver, including on-chip split-Thevenin termination using the ODT attribute. The source termination feature (OUTPUT_IMPEDANCE) provides the option of 40 Ω, 48 Ω, or 60 Ω of tuned driver impedance in HP I/O banks. The default value of the driver output impedance is 48 Ω.
