Description
AI
The ONET1101L is a high-speed, 3.3-V laser driver designed to directly modulate a laser at data rates from 2 Gbps to 11.3 Gbps.
The device provides a two-wire serial interface that helps digital control of the modulation, plus bias currents and cross point, eliminating the need for external components. An optional input equalizer can be used for equalization of up to 300 mm (12") of microstrip or stripline transmission line on FR4 printed circuit boards.
The ONET1101L includes an integrated automatic power control (APC) loop, plus circuitry to support laser safety and transceiver management systems.
The laser driver is characterized for operation from -25°C to 100°C case temperature and is available in a small footprint using a 4mm × 4mm, 24-pin RoHS-compliant QFN package.
