Description

The MAX3701 is a laser driver designed to drive a common-cathode laser for the next generation of high-capacity blue DVD applications. It includes a programmable current source for generating a laser bias current, and four programmable data channels for programming the write current levels. The MAX3701 also includes an RF current source with programmable frequency and amplitude control. The RF source, together with the bias generator, provides a disc read waveform. All programmable currents are internally summed together, and can be disabled from a single enable pin. A transimpedance amplifier and a sample-and-hold circuit are available to be used with a monitor photodiode as part of an optical power-control (OPC) loop. Each of the four programmable inputs can contribute up to 200mAP-P current with a total output current limit of 200mA into a blue laser diode. The four fast-switching channels accept single-ended CMOS, and can write at speeds as high as 400Mbps. The RF circuit delivers an output signal between 200MHz and 600MHz. The MAX3701 is available in a 5mm x 5mm 32-pin thin QFN package.
