Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Characteristics
(Minimum and maximum values specified over operating case temperature range at 50% duty cycle data signal.
Typical values are measured at room temperature unless otherwise noted.)
Table 2. Electrical Characteristics
1. With V
2. Inputs are ac-coupled into an equivalent input impedance of 50 .
3. Single-ended or differential operation may be used. If the inputs are driven single-ended, the unused inputs (
4. Clocked operation is normally enabled and only requires an external voltage to disable. For nonclocked operation, pin 5 must be tied to V
5. With clocked operation, the optical output changes state with the rising edge of the input clock signal. The skew is measured with the rising
6. The transmitter is normally enabled and only requires an external voltage to disable.
7. This alarm will go active when the bias current to the laser has increased 50% or more from its beginning-of-life (BOL) value.
8. This voltage is measured from Pin 3 to V
9. This voltage is measured from Pin 2 to V
