Some I/O standards (e.g., HSTL Class IV) require an output termination to V

DCI can provide an output termination to V
only controls the impedance of the termination, but not the driver. Both GTL and HSTL
standards need 50 Ω external reference resistors. The DCI I/O standards supporting
drivers with single termination are: GTL_DCI, GTLP_DCI, HSTL_IV_DCI, and
HSTL_IV_DCI_18.
