Texas Instruments ONET1101L
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. The ONET1101L includes an integrated automatic power control (APC) loop, plus circuitry to support laser safety and transceiver management systems.| Part No. | ONET1101L |
