Описание

The MAX3646ETG+T is a 155Mbps to 622Mbps SFF/SFP laser driver with extinction ratio control in 24 pin TQFN package. The MAX3646 is a +3.3V laser driver designed for multirate transceiver module with data rates from 155Mbps to 622Mbps. Lasers can be DC-coupled to the MAX3646 for reduced component count and ease of multirate operation. Laser extinction ratio control combines the features of automatic power control, modulation compensation and built-in thermal compensation. The APC loop maintains constant average optical power. Modulation compensation increases the modulation current in proportion to the bias current. These control loops, combined with thermal compensation, maintain a constant optical extinction ratio over temperature and lifetime. It accepts differential data input signals. External resistors set the required laser current levels. It provides transmit disable control (TX_DISABLE), single-point fault tolerance, bias-current monitoring and photocurrent monitoring.

• Power-supply current is 47mA
• Operating temperature range from -40°C to 85°C
• Modulation current is 85mA
• Bias current is 100mA
• Latched failure output (TX_FAULT) to indicate faults
• Compliant with the SFF-8472 transmitter diagnostic and SFP MSA timing requirements
• On-chip temperature compensation
• Self-biased inputs for AC-coupling
• Ground referenced current monitors
• Laser shutdown and alarm outputs
