General Description

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.

Output waveform control, in the form of cross point control and independent over- and undershoot capability on the rising and falling edges is also available to improve VCSEL edge speeds and the optical eye diagram.
