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.

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

Applications
• Proprietary 120 Gb/s intra-system parallel optics
• Proprietary 12-lane optical modules and CWDM
• 10GbE, 10GFC, OC-192 VSR parallel optics
