A 15mW, 155Mb/s CMOS Burst-Mode Laser Driver with Automatic Power Control
01 December 1999
The design of a low-power, burst-mode laser driver for use in passive optical networks (PON) is described. The laser driver can operate at 50 Mb/s or 155 Mb/s. It features automatic control of the optimal output power (APC) as well as end-of-life detection of the laser diode. The driver is implemented with a single chip in 3.3 V, 0.5 micron CMOS technology. Special design techniques for low-power consumption and burst-mode operation are used.
