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.
