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. This device is intended to be used with Micrel's MIC3001 Optical Transceiver Management IC, which allows for both modulation and bias current control and monitoring, APC (Automatic Power Control), and temperature compensation.
