Output Characteristics and Operating Conditions
Slew Rate Definitions for Differential Output Signals
The differential output driver is summarized in Table 48 (page 67). With the reference
load for timing measurements, the output slew rate for falling and rising edges is de-
fined and measured between V_OL(AC) and V_OH(AC) for differential signals.
