Optical


Optical communication networks use fiber optic cable and laser LEDs to provide high speed data communication channels for wide area networks and smaller, high capacity, campus or data-center communication networks.

The interface to the optical cable requires specific physical layer drivers and receivers and specialized controllers to manage signal conversion. Our in-house SiGe BiCMOS process allows us to provide a full family of laser drivers, controllers, transimepdance amplifiers (TIAs), limiting amplifiers, and timing circuits for optical networking.



Applications


Optical Transceivers

We offer optimized physical media ICs for every optical application, including laser drivers, transimpedance amplifiers, limiting amplifiers, clock and data recovery (CDR) circuits, serializers, and deserializers. Our optical module ICs support Ethernet, SONET/SDH, SFF/SFP, SFP+, and QSFP+ standards. We provide the most complete product line of PON (EPON, GPON, GEPON) solutions.

Optical Transceivers for Optical Module Applications


Featured Products


11.32Gbps Transceiver with Dual CDRs, Digital Monitors, and DC-Coupled Laser Driver

MAX3955

This 11.3Gbps, highly-integrated, low-power transceiver with dual CDRs, and digital diagnostics monitoring (DDM) is designed for next-generation SONET transmission systems.

Low-Power Transimpedance Amplifier for 10GBASE-SR Applications

MAX3797

This device is a low-power transimpedance amplifier incorporating an automatic gain control (AGC) architecture and is designed for optical transmission systems at data rates up to 10.3125Gbps and for use with PIN diodes.

Optical Microcontroller

DS4830A

This 16-bit microcontroller with a unique peripheral set supports optical applications that require high-resolution conversion of many analog signals and digital signal processing (DSP) of those signals, high-speed data communication to an external host, and ultra-low power dissipation.

SFF/SFP Laser Driver with Extinction Ratio Control

MAX3738

This laser driver is designed for multirate transceiver modules with data rates from 1Gbps to 4.25Gbps. Lasers can be DC-coupled to the MAX3738 for reduced component count and ease of multirate operation.
