Supported I/O Standards and Terminations
HSTL_ II_DCI and HSTL_ II_DCI_18
HSTL_II_DCI and HSTL_II_DCI_18 provide on-chip split thevenin termination powered
from V
CCO
, creating an equivalent termination voltage of V
CCO
/2, and are intended for
use in bidirectional links.
HSTL_ II_T_DCI and HSTL_ II_T_DCI_18
HSTL_ II_T_DCI and HSTL_ II_T_DCI_18 provide on-chip split-thevenin termination
powered from V
CCO
that creates an equivalent termination voltage of V
CCO
/2 at the
receiver when the driver is 3-stated. When the driver is not 3-stated, these two standards
do not have termination.
DIFF_HSTL_I and DIFF_HSTL_I_18
Differential HSTL class-I pairs complementary single-ended HSTL_I type drivers with a
differential receiver, and are intended to be used in unidirectional links.
DIFF_HSTL_I_DCI and DIFF_HSTL_I_DCI_18
Differential HSTL class-I pairs complementary single-ended HSTL_I type drivers with a
differential receiver, including on-chip split-thevenin termination, and are intended to be
used in unidirectional links.
DIFF_HSTL_ II and DIFF_HSTL_II_18
Differential HSTL class-II pairs complementary single-ended HSTL_II type drivers with a
differential receiver. Differential HSTL class-II is intended to be used in bidirectional links.
