Output Characteristics and Operating Conditions
Slew Rate Definitions for Differential Output Signals
The differential output driver is summarized in Table 48 (page 0±). With the reference
load for timing measurements, the output slew rate for falling and rising edges is de-
fined and measured between VOL(AC) and VOH(AC) for differential signals.
