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 = Z0)
to the VCCO/2. The untuned on-die source termination feature
(OUTPUT_IMPEDANCE) with optional 40 Ω, 48 Ω, or 60 Ω of driver impedance is available in HP
I/O banks only. In XP5IO I/O banks, termination is always calibrated. The default value of
the driver output impedance is 48 Ω.
