Description

The ONET1151L device is a 3.3-V laser driver designed to directly modulate a laser at data rates from 1 to 11.3 Gbps.

The device provides a 2-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, de-emphasis, and output termination resistance are available to improve the optical eye mask margin. An optional input equalizer can be used for equalization of up to 150 mm (6 in.) of microstrip or stripline transmission line on FR4-printed circuit boards. The device contains internal ADC and DACs to eliminate the need for special purpose microcontrollers.

Features

1. Digitally Selectable Modulation Current up to 85 mApp (10-Ω Load)

2. Digitally Selectable Bias Current up to 100-mA Source or Sink

3. 2-Wire Digital Interface With Integrated Digital-to-Analog Converters
