DS1876

SFP Controller with Dual LDD Interface

General Description

Features

S Meets All SFF-8472 Transmitter Control and

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

Monitoring Requirements

S Six Analog Monitor Channels: Temperature, V

PMON1, BMON1, PMON2, BMON2

PMON_ and BMON_ Support Internal and

External Calibration

Scalable Dynamic Range

Internal Direct-to-Digital Temperature Sensor

Alarm and Warning Flags for All Monitored

Channels

channels monitor V , temperature, and four external

monitor inputs that can be used to meet all monitoring

requirements.

S Six Quick Trips for Fast Monitoring of Critical

Functions for Laser Safety

Applications
