DESCRIPTION

The ONET1141L is a high-speed, 3.3V electroabsorption modulator driver designed to bias and modulate an

electroabsorptive modulated laser (EML) at data rates from 1 Gbps up to 11.3 Gbps.

The device provides a two-wire serial interface which allows digital control of the modulation and bias currents,

eliminating the need for external components. Output waveform control, in the form of cross-point adjustment

and rise and fall time adjustment are available to improve the optical eye mask margin. An optional input

equalizer can be used for equalization of up to 150mm (6”) of microstrip or stripline transmission line on FR4

printed circuit boards. The device contains internal analog to digital and digital to analog converters to eliminate

the need for special purpose microcontrollers.

The ONET1141L includes an integrated automatic power control (APC) loop which compensates for variations in

laser average optical power over voltage and temperature and circuitry to support laser safety and transceiver

management systems.

The modulator driver is characterized for operation from –40°C to 100°C case temperatures and is available in a

small footprint 4mm × 4mm 24 pin RoHS compliant QFN package.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
