SFP Controller with Dual LDD Interface

19-5153; Rev 0; 2/10

General Description

The DS1876 controls and monitors all functions for

dual transmitter modules. The memory map is based

on SFF-8472. The DS1876 supports APC and modula-

tion control and eye safety functionality for two laser

drivers. It continually monitors for high output current,

high bias current, and low and high transmit power to

ensure that laser shutdown for eye safety requirements

are met without adding external components. Six ADC

channels monitor VCC, temperature, and four external

monitor inputs that can be used to meet all monitoring

requirements.

Applications
