SSTL18_II_T_DCI (1.8V) Split-Thevenin Termination
Table 6-35
Table 6-35: Differential SSTL (1.8V) Class II DC Voltage Specifications
Figure 6-86
SSTL18_II_T_DCI (1.8V) with on-chip split-Thevenin termination. In this bidirectional I/O
standard, when 3-stated, the termination is invoked on the receiver and not on the driver.
Because the Thevenin termination on the I/O is disabled for a driving I/O, the line is
equivalent to the SSTL18_I termination scheme. This allows the line to be driven by the
weaker SSTL class I driver. The SSTL18_II_T_DCI standard behaves like a normal
SSTL18_II I/O in a bidirectional environment but has the advantage of lower drive
strength and lower power consumption due to the optimized termination circuit.
