Maxim Integrated (MAX3996CTP+) Laser Diode Driver, SFP VCSEL

Product Overview 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. Supply voltage range from 3V to 5.5V Operating temperature range from 0°C to 70°C Contains bias generator, laser modulator and comprehensive safety features Automatic power control and integrated safety circuits Temperature compensation of modulation current Compliant with SFF and small form factor pluggable (SFP) multisource agreements (MSA) Supply current of 47mA (VCC=3.3V, IMOD=15mA) & 52mA (VCC=5.5V, IMOD = 30mA, RMODSET=2.37Kohm) Random jitter of 2psRMS Transmit disable, redundant shutdown and laser bias monitoring Switch up to 30mA of laser modulation current and sink up to 60mA bias current Applications Communications & Networking Product Information Laser Driver Type: SFP VCSEL Driver Case Style: TQFN No. of Pins: 20Pins Supply Voltage Min: 3V Supply Voltage Max: 5.5V Product Range: - MSL: MSL 1 - Unlimited
