max3701 2x 4 _______________________________________________________________________________________ note 1: v cco should be selected to keep a minimum headroom of 3.0v for the driver output, out. 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 7: i dc = 50ma and i ac = 50ma p-p . 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.
