T hese fixed values for Pipeline Delay are valid under conditions where t
and
τ
–t
are met. If either t
10
or
τ
–t
11
are not met, the part will operate but the Pipe-
line Delay is increased by 2 clock cycles for 2:1 mode after calibration cycle is performed.

Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition. Output rise/fall time measured between the
10% and 90% points of full-scale transition. Settling time measured from the 50% point of full-scale transition to the output remaining within
±
1 LSB. (Settling time
does not include clock and data feedthrough.)

t
23
and t
are measured with the load circuit of Figure 1 and defined as the time required for an output to cross 0.4 V or 2.4 V.
9
t
is derived from the measured time taken by the data outputs to change by 0.5 V when loaded with the circuit of Figure 1. T he measured number is then extrapo-
lated back to remove the effects of charging the 100 pF capacitor. T his means that the time, t
25
, quoted in the T iming Characteristics is the true value for the device
and as such is independent of external databus loading capacitances.
