Notes:

1. The Laser Reset Voltage is the voltage level below which the VCCT voltage must be lowered to cause the laser driver circuit to reset

from an electrical/optical shutdown condition to a proper electrical/optical operating condition. The maximum value corresponds

to the worst-case highest VCC voltage necessary to cause a reset condition to occur. The laser safety shutdown circuit will operate

properly with transmitter VCC levels of 3.5 Vdc ≤ VCC ≤ 7.0 Vdc.

2. Power dissipation value is the power dissipated in the receiver itself. It is calculated as the sum of the products of VCC and ICC

minus the sum of the products of the output voltages and currents.

3. These outputs are compatible with 10 K, 10 KH, and 100 K ECL and PECL inputs.

4. These are 20-80% values.
