• Continuous output monitoring
• Power dissipation <1500 mW (for typical application)
• Low cost LQFP48 plastic package.
APPLICATIONS
• Digital fibre optical modulation driver in STM16/OC48
short, medium and long haul optical transmission
systems
• Optical modulation driver in high-speed data networks
• High current driver for electro-optical converters
• High current electrical line driver.
GENERAL DESCRIPTION
The OQ2545 is a driver IC intended to be used with a
directly modulated laser diode or with an Electro
Absorption Modulator (EAM) in SDH/SONET 2.5 Gbits/s
optical transmission systems.
The IC features differential data inputs. Loop mode inputs
are provided for system testing, along with an output for
continuous monitoring. In addition, the OQ2545HP
features differential clock inputs for internal retiming
resulting in a better jitter performance.
The IC has bias and modulating current outputs, the levels
of which can be set separately. As an additional safety
measure, the active HIGH-level input for automatic laser
shutdown (pin ALS) can be used to switch off the laser
modulation and bias currents.
Although the IC is intended for 2.5 Gbits/s optical
transmission systems, it can be used in any application
requiring high current drive at high frequencies.
The IC is transparent from input to output.
