DCI Usage Examples

7.
The behavior of a DCI 3-state outputs is as follows:
If a LVDCI or LVDCI_DV2 driver is in 3-state, the driver is 3-stated. If a driver with single
or split termination is in 3-state, the driver is 3-stated but the termination resistor remains.
The following section lists actions that must be taken for each DCI I/O standard.

•
The value of the external reference resistors should be selected to give the desired
output impedance. If using GTL_DCI, HSTL_DCI, or SSTL_DCI I/O standards, then
the external reference resistors should be 50 Ω .
The values of the reference resistors must be within the supported range
(20 Ω – 100 Ω).
Follow the DCI I/O banking rules:

Single termination and split termination, controlled impedance driver, and
controlled impedance driver with half impedance can co-exist in the same bank.
