The MAX3735AETG is a high performance, fixed-frequency, laser driver specifically designed to meet the performance requirements of 10Gbps Ethernet and Fibre Channel applications. The IC provides current outputs with a peak spectral bandwidth of 2 GHz and a slew rate of 8V/ns, making it well-suited for electro-optic modulation in cutting edge designs. The MAX3735AETG is the ideal solution for an array of applications in need of a high performance and reliable laser driver.

The MAX3735AETG laser driver has two independent channels that can each produce up to 65mA of current output into an external laser diode. Each channel has a dedicated output stage with separately programmable bias and modulation voltage outputs. The optional current limit feature allows for precise laser diode bias current regulation, ensuring safe and reliable operation of the laser diode in any application. The device also offers softstart and enable/disable control for both channels, allowing for easy integration into an FPGA or microcontroller.

The MAX3735AETG operates from a single 3.3V supply and features a 10-bit digital to analog converter (DAC) with adjustable current and modulation voltage output resolution. The DAC allows the device to be programmed with up to 256 discrete current and modulation levels, providing extra flexibility in the design process. Additionally, the device offers power down and sleep modes to reduce power consumption.

In order to ensure reliable operation of the laser driver, the device is designed with protection features against external interference and malfunction. The laser driver features low-noise sequence control for safety and reliability. The internal reference voltage is designed to be stable over temperature and keep current level accuracy over temperature range. The thermal shutdown feature provides protection against high temperature operation and will disable the driver when the junction temperature exceeds a certain threshold. Additionally, the device offers short-circuit protection, electrostatic discharge (ESD) protection and EMI protection.

The MAX3735AETG is a powerful and advanced laser driver well suited for applications requiring high-speed laser control in 10Gbps Ethernet and Fibre Channel. The device's high-speed output stage, programmable DAC, and comprehensive protection features make it an ideal choice for a range of demanding design applications. The combination of features and flexibility makes the MAX3735AETG a versatile and reliable solution in the PMIC - Laser Drivers field.
