Texas Instruments ONET1151L
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. The device contains internal ADC and DACs to eliminate the need for special purpose microcontrollers.| Part No. | ONET1151L |
