SY88992L 3.3V, 4.25Gbps VCSEL Driver General Description Features The SY88992L is a single supply 3.3V, low power Up to 25mA modulation current consumption, small-form factor VCSEL driver ideal for Operates from 100Mbps to 4.25Gbps use in datacom applications Ethernet, GbE (Gigabit Peaking with variable duration option for better Ethernet), and FC (Fibre Channel) applications that VCSEL response operate from 100Mbps up to 4.25Gbps. The Dual peaking, on the rise and falling edges modulation current is set by applying an external voltage at the IM SET pin. The driver features an Peaking current proportional to modulation current adjustable peaking option with variable amplitude and Easy modulation current setting duration to improve VCSEL edge response. The driver Fully controllable with Micrel MIC3001 can deliver modulation current up to 25mA and a Small (3mm x 3mm) 16 pin QFN package peaking current up to 35% of the modulation current. This device is intended to be used with Micrels Applications MIC3001 Optical Transceiver Management IC, which allows for both modulation and bias current control and Multirate LAN, SAN applications up to 4.25Gbps: monitoring, APC (Automatic Power Control), and Ethernet, GbE, FC temperature compensation.
