Texas Instruments ONET8501V
The ONET8501V is a high-speed, 3.3V laser driver designed to directly modulate VCSELs at data rates from 2 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. The ONET8501V includes an integrated automatic power control (APC) loop as well as circuitry to support laser safety and transceiver management systems.| Part No. | ONET8501V |
