The MAX3643 burst-mode laser driver provides bias and modulation current drive for PON burst-mode ONT applications. It is specifically designed for use with a low-cost external controller for the APC (and if desired, AMC) loop. A high-speed differential burst-enable input enables the driver to switch the laser from a dark (output off) condition to full on-co.
♦ 10mA to 85mA Modulation Current ♦ 1mA to 70mA Bias Current ♦ Monitor Diode Sample and Hold ♦ 45ps Output Transition Time ♦ 2ns Turn-On/-Off Time ♦ Reference Voltage Generator ♦ LVPECL High-Speed Inputs (Data, Burst Enable)
