HSTL_I and HSTL_ I_18 use V CCO /2 as a parallel-termination voltage (V TT ).

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 , 48 W, or 60 of driver impedance is available in HP I/O banks. The default value of the driver output impedance is 48 .
