PON Triplexer Control and

Monitoring Circuit

____________________________________________________________________

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.
