MAX3996CTP+

The MAX3996CTP+ is a 2.5Gbps VCSEL and laser driver in 20 pin TQFN package. It is a high speed laser driver for small form factor (SFF) fibre optic LAN transmitters. Automatic power control (APC) adjusts laser bias current to maintain average optical power regardless of changes in temperature or laser properties. The driver accommodates common anode or differential laser configurations. The output current range of the MAX3996 is appropriate for VCSELs and high efficiency edge emitting lasers. It operates up to 3.2Gbps. Adjustable temperature compensation is provided to keep the optical extinction ratio within specifications over operating temperature range. Low deterministic jitter (9psP-P) combined with fast edge transition (65ps) provides excellent margins compared to industry standard transmitter eye masks. The MAX3996 is used in fibre channel optical transmitters, VCSEL transmitters, gigabit Ethernet optical transmitters, ATM LAN optical transmitters and 10gigabit Ethernet WWDM.
