HFBR-53D3 Family, 850 nm VCSEL
Transmitter Electrical Characteristics
(TA = 0°C to +70°C, VCC = 4.75 V to 5.25 V)
Receiver Electrical Characteristics
(TA = 0°C to +70°C, VCC = 4.75 V to 5.25 V)
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 V dc < VCC < 7.0 V dc.
2.
Receiver Supply Current and Power Dissipation do not include current and power in external 270 ohm terminating resistors.
3.
These outputs are compatible with 10 K, 10 KH, and 100 K ECL and PECL inputs.
4.
These are 20-80% values.
