General Description

The 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 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.
