Detailed Description
The DS1865 integrates the control and monitoring func-
tionality required to implement a PON system using
Maxim’s MAX3643 compact burst-mode laser driver.
The compact laser driver solution offers a considerable
cost benefit by integrating control and monitoring fea-
tures in the low-power CMOS process, while leaving
only the high-speed portions to the laser driver. Key
components of the DS1865 are shown in the
Block
Diagram and described in subsequent sections. Table 1
contains a list of acronyms used in this data sheet.
APC Control
BIAS current is controlled by an average power control
(APC) loop. The APC loop uses digital techniques to
overcome the difficulties associated with controlling
burst-mode systems.
