Driver with Termination to V
Figure 6-13
X-Ref Target - Figure 6-13
Some I/O standards, such as HSTL Class II, require an output termination to V

X-Ref Target - Figure 6-14
DCI can provide output termination to V
the impedance of the termination, but not the driver. Both HSTL and SSTL standards need
50 Ω external reference resistors. The DCI output standards supporting drivers with split
termination are shown in
