SY88992L

SY88992L 3.3V, 4.25Gbps VCSEL Driver 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. 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. All support documentation can be found on Micrel’s web site at: www.micrel.com. 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 MLF™ package Applications Multirate LAN, SAN applications up to 4.25Gbps: Ethernet, GbE, FC SFF, SFP Modules Markets Datacom ________________________________________________________________ Typical Application www.DataSheet4U...
