Tóm tắt
Fast level monitoring circuitry was implemented in an intelligent 155Mb/s burst-mode laser driver chip suitable for PON applications. The chip can regulate the launched optical power of an external laser diode to a required level within 2.6 /spl mu/s, when the laser and its driver are powered up and connected to the network for the first time. A 3.3 V digital 0.35 /spl mu/m CMOS process was used for the design of this generic chip, which supports most commercially available lasers. No external adjustable components are required.
