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.
