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.

The MAX3935† is designed to drive an electro-absorption modulator (EAM) at data rates up to 10.7Gbps. It provides programmable output levels through externally adjustable bias and modulation currents. This EAM driver MAX3935† is fabricated with Maxim's in-house second-generation SiGe process.

The MAX3935† accepts differential ECL or ground-referenced CML clock and data-input signals. Inputs are terminated with on-chip 50 resistors. An input-data retiming latch can be used to reject input-patterndependent jitter if a clock signal is available.

The driver MAX3935† can modulate EAM devices at amplitudes up to 3.0VP-P when the device impedance is 50. Typical (20% to 80%) edge speeds are 34ps. The output has an on-chip 75 resistor for back termination. The MAX3935† allows for an EAM bias voltage up to 1.2V.

The MAX3935† also includes an adjustable pulse-width control circuit to precompensate for asymmetrical EAM characteristics.
