6.3 Differential Output Slew Rate
With the reference load for timing measurements, output slew rate for falling and rising edges is defined and
measured between VOLdiff (AC) and VOHdiff (AC) for differential signals as shown in Table and Figure .
Differential Output Slew Rate Definition
Note:
Output slew rate is verified by design and characterization, and may not be subject to production test.
