General Description
The SY88992L is a single supply 3.3V, low power consumption, small-form factor VCSEL driver ideal for use in datacom applications; Ethernet, GbE (Gigabit Ethernet), and FC (Fibre Channel) applications that operate from 100Mbps up to 4.25Gbps. The modulation current is set by applying an external voltage at the IM_SET pin. The driver features an adjustable peaking option with variable amplitude and duration to improve VCSEL edge response. The driver can deliver modulation current up to 25mA and a peaking current up to 35% of the modulation current.

Features
• Up to 25mA modulation current
• Operates from 100Mbps to 4.25Gbps
• Peaking with variable duration option for better VCSEL response
• Dual peaking, on the rise and falling edges
• Peaking current proportional to modulation current
• Easy modulation current setting
• Fully controllable with Micrel MIC3001
• Small (3mm x 3mm) 16 pin QFN package

Applications
• Multirate LAN, SAN applications up to 4.25Gbps: Ethernet, GbE, FC
• SFF, SFP Modules
