DESCRIPTION

· The TZA3011 is a fully integrated laser driver for optical transmission systems, supporting data rates up to 3.2 Gbit/s.

· It incorporates all necessary control and protection functions, requiring very few external components and featuring low power dissipation.

· The device uses a dual-loop control for average monitor current (150 µA to 1300 µA) and extinction ratio (5 to 15).

· Manufactured in Philips BiCMOS RF process, available in HBCC32 package or as bare die.

· TZA3011A is designed for AC-coupled laser diodes with 3.3 V supply, while TZA3011B supports DC-coupled laser diodes with 3.3 V and 5 V supplies.

FEATURES

· Supports data rates from 30 Mbit/s to 3.2 Gbit/s.

· Bias and modulation currents up to 100 mA.

· Rise and fall times typically 80 ps, jitter below 20 ps.

· Modulation output voltage up to 2 V dynamic range.

· Compatible with PECL, LVPECL, and CML data and clock inputs.

· 3.3 V supply voltage, with specific models for AC and DC-coupled lasers.

APPLICATIONS

· Suitable for high-speed optical transmission systems.

· Ideal for applications requiring precise laser control with minimal external components.

· Can be used in systems with both AC and DC-coupled laser diodes, depending on the model.
