Note 1.
AC characteristics are guaranteed by design and characterization.
Note 2.
Measured using 750mV source, 50% duty cycle clock source.
Note 3.
Tested using environment of Figure 6.
Note 4.
Refer to “Typical Operating Characteristics” for output swing performance.
Note 5.
The delays of the individual bits are cumulative.
Note 6.
Duty cycle skew guaranteed only for differential operation measured from the crosspoint of the input edge to the crosspoint of the correspond-
ing output edge.
Note 7.
Setup time defines the amount of time prior to an edge on IN, /IN that the D[0:9] bits must be set to guarantee the new delay will occur for that
edge.
Note 8.
Setup time is the minimum that /EN must be asserted prior to the next transition of IN, /IN to prevent an output response greater than
±75mV
to that IN, /IN transition.
Note 9.
Hold time is the minimum time that /EN must remain asserted after a negative going IN or a positive going /IN to prevent an output response
greater than
±75mV to that IN, /IN transition.
Note 10. Release time is the minimum time that /EN must be deasserted prior to the next IN, /IN transition to ensure an output response that meets the
specified IN to Q propagation delay and transition times.
Note 11. This is the amount of generated jitter added to an otherwise jitter free clock signal, going from IN, /IN to Q, /Q, where the clock may be any
frequency between 0.0 and 2.5GHz.
