TZA3001BHL datasheet


Description :

The TZA3001AHL, TZA3001BHL and TZA3001U are fully integrated laser drivers for STM4/OC12 (622 Mbits/s) systems, incorporating the RF path between the data multiplexer and the laser diode. Since the dual loop bias and modulation control circuits are integrated on the IC, the external component count is low. Only decoupling capacitors and adjustment resistors are required.

The TZA3001AHL features an alarm function for signalling extreme bias current conditions. The alarm low and high threshold levels can be adjusted to suit the application using only a resistor or a current Digital-to-Analog Converter (DAC).


1. RF output current sinking capability of 60 mA
2. Bias current sinking capability of 90 mA
3. Power dissipation of 430 mW (typical value)
4. Low cost LQFP32 plastic package
5. Single 5 V power supply.
6. Automatic laser shutdown
7. Few external components required

ESD failures can be prevented by always wearing wrist straps, only using a grounding workplace, and following strict anti-static guidelines when handling the laser diode Safety Advice This laser diode emits highly concentrated blue light which can be hazardous to the human eye and skin. This diode is classified as CLASS 4 laser product according to IEC 60825-1 and 21 CFR Part 1040.10 Safety Standards. Operating Considerations Operating the laser diode outside of its maximum ratings may cause failure or a safety hazard. The diode may be damaged by excessive drive currents or switching transients. If the diode is operated using a power supply, it is strongly recommended to connect the diode with the output voltage set to zero. The voltage should then be increased slowly and with great caution, while at the same time carefully monitoring the laser diodes output power and drive current. The laser diode will show accelerated degradation with increased temperature, and it is advised to keep the case temperature low therefor, by means of heat sinking the device. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice 4 […]
