RZQ of 240��±1% with RZQ/7 enabled (default 34� driver) and is applicable after proper ZQ calibration has been performed at a stable temperature and voltage (V DDQ = V DD; V SSQ = V SS). 2. V REF = V DDQ/2; slew rate @ 5 V/ns, interpolate for faster slew rate. 3. See Figure 29 (page 69) for the test load configuration. 4. See Table 51 (page 71) for the output slew rate. 5. See Table 38 (page 62) for additional information. 6. See Figure 28 (page 69) for an example of a differential output signal.

It is not intended to be a precise representation of a particular system environment or a depiction of the actual load presented by a production tester. System designers should use IBIS or other simulation tools to correlate the timing reference load to a system environment.
