NXP USA Inc. TZA3011BVH/C2,557

Description
The TZA3011 is a fully integrated laser driver for optical transmission systems with data rates up to 3.2 Gbit/s. It incorporates all necessary control and protection functions for laser driver applications, requiring few external components and low power dissipation. The dual-loop controls the average monitor current in a programmable range from 150 μA to 1300 μA and the extinction ratio in a programmable range from 5 to 15 (linear scale).
