说明

The MAX3930/MAX3931/MAX3932 are designed for direct modulation of laser diodes at data rates up to 10.7Gbps. They provide adjustable laser bias and modulation currents and are implemented using Maxim's second-generation in-house SiGe process.

The MAX3930 accepts differential CML clock and data input signals and includes 50Ω on-chip termination resistors. It delivers a 1mA to 100mA laser bias current and a 20mA to 100mA modulation current with a typical (20% to 80%) 25ps rise time. An input data retiming latch can be used to reject input pattern-dependent jitter if a clock signal is available.

The MAX3931/MAX3932 have an alternate pad out with respect to the MAX3930. The MAX3931 includes the series damping resistor RD on chip.

The MAX3930/MAX3931/MAX3932 also include an adjustable pulse-width control circuit to minimize laser pulse-width distortion.
