Note 2: The input pulse width has to be sufficient to achieve the desired output performance.

Note 3: Operating frequency of the set inputs (V1, V2, V3, V4, V5) is

≤ 1MHz.

Note 4: Conditions are that no single channel can be programmed beyond the maximum output level. Also, all five channels must _

be programmed so their total output current (I1 + I2 + I3 + I4 + I5) is below the maximum output level. It is important that __

this condition is assumed even for those channels not being used (i.e., those channels with inactive data signal).

Note 5: AC characteristics are guaranteed by design and characterization.

Note 6: Read oscillator is bandwidth limited, -3dB at approximately 400MHz (see the Typical Operating Characteristics).

Note 8: A compensation network to match the laser diode is required to achieve the overshoot specifications, otherwise the over-

shoot can be significantly higher. (See Figure 1.)
