If either the temperature or voltage changes after I/O calibration, then the tolerance
limits listed in Table 30 (page 55) and Table 31 can be expected to widen according to
Table 32 and Table 33 (page 57).
Table 33: ODT Temperature and Voltage Sensitivity
ODT loading differs from that used in AC timing measurements. The reference load for
ODT timings is shown in Figure 24. Two parameters define when ODT turns on or off
synchronously, two define when ODT turns on or off asynchronously, and another de-
fines when ODT turns on or off dynamically. Table 34 outlines and provides definition
and measurement references settings for each parameter (see Table 35 (page 58)).
ODT turn-on time begins when the output leaves High-Z and ODT resistance begins to
turn on. ODT turn-off time begins when the output leaves Low-Z and ODT resistance
begins to turn off.
1. Values assume an RZQ of 240Ω (±1%).
