- Single +3.3 V supply dissipating 70 m W per channel 12-channel VCSEL driver operates from DC to 6.25Gb/s Description
The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance. The demand for 40 Gb/s bandwidth and beyond fuels the growth of shortreach 10 Gb/s infrastructures within high-end telco and data routers, switches, servers and other proprietary chassis-to-chassis links. The Zarlink ZL63039 12x6.25Gb/s VCSEL Driver is a 12-channel VCSEL driver designed for various parallel optics and CWDM PMD applications. It consists of a DC-coupled amplifier with selectable threshold and modulation currents optimized for driving mercially available, mon cathode VCSELs from a single +3.3 V supply. Individual channel settings are used to control the threshold and modulation drive current and their temperature coefficients, allowing the optical output power and extinction ratio to be optimized. A selectable analog multiplexer provides...
