GENERAL DESCRIPTION The CS6706 is a high-speed fiber optic VCSEL driver suited for applications up to 1.25Gbps. The CS6706 accepts differential PECL inputs, and includes a CMOS disable pin for bias and modulation current control. Further, the bias and modulation current can be set independently via two external resistors, and the rise/fall time can also be adjusted using external resistors. A monitor photodiode can be incorporated in the application circuit to ensure a stable laser power source. Any failure of the laser is detected using the two on-chip window comparators. Once a failure is detected, the laser power safety switch will be triggered and can only be reset by a power off condition.
