Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX3934 is a compact +5V or -5.2V laser driver designed to directly modulate a laser diode at data rates up to 10.7Gbps. The driver MAX3934 provides externally programmable laser biasing and modulation currents. DC-coupling with an integrated compensation network, consisting of a series-damping resistor and a shunt RC, makes the MAX3934 ideal for compact subassemblies.
The MAX3934 accepts a differential CML or PECL data signal and includes 50 on-chip termination resistors. It delivers a 1mA to 60mA laser bias current and a 20mA to 80mA laser modulation current with a typical edge speed of 25ps (20% to 80%). A high-bandwidth, fully differential signal path is internally implemented to minimize jitter accumulation. Additional features of MAX3934 include a data polarity control, bias current, and modulation current monitors.
