www.DataSheet4U.com PX6419 12x10 Gb/s VCSEL Driver Product Brief January 2005 Features 12x10 Gb/s VCSEL Driver Single +3.3V supply dissipating 142 mW per channel Serial digital interface for global and individual channel control Individual channel control for enable, modulation and bias current On-chip adjustable VCSEL temperature compensation Adjustable output current waveform for VCSEL jitter reduction Analog control input for closed-loop optical power optimization VCSEL open/short detection with autonomous fault handling 250-micron channel pitch matches optical ribbon fiber and array VCSELs Differential CML inputs with on-chip termination Description The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance. The demand for 1 Tb/s+ WAN bandwidth fuels the growth of short-reach 120 Gb/s infrastructures within high-end telco and datacom routers, switches, servers and other proprietary chassis-to-chassis links. The Zarlink PX6419 12X10 Gb/s VCSEL Driver* is a 12-channel VCSEL driver designed for various 12x10 Gb/s, 120 Gb/s parallel optics and CWDM PMD applications. It consists of a DCcoupled amplifier with selectable modulation and bias currents optimized for driving commercially available, common cathode VCSELs from a single +3.3 V supply. Individual channel settings are used to control the modulation and bias current and their temperature coefficients, allowing the optical output power and extinction ratio to ...
