DIFF_HSTL_I and DIFF_HSTL_I_18

Differential HSTL class-I pairs complementary single-ended HSTL_I type drivers with a differential receiver.

Optional untuned split input ODT provides Thevenin equivalent resistance of R (where R = Z ₀ ) to the V _CCO /2. The untuned on-die source termination feature (OUTPUT_IMPEDANCE) with optional 40 Ω , 48 W, or 60 Ω of driver impedance is available in HP I/O banks. The default value of the driver output impedance is 48 Ω .
