Analog Devices introduced five integrated circuit solutions, expanding the company's extensive family of products for optical networking applications. These new transmit/receive and monitoring/control IC solutions provide important design alternatives for the development of components and modules for optical network systems. Analog Devices will demonstrate the new ICs at the Optical Fiber Communication Conference on March 25 - 27, 2003 in Atlanta, Georgia.
The new ICs for transmit and receive applications include the ADN2812, a continuous tuning clock and data recovery IC, and the ADN2849 and ADN2859 10.7 Gbps external modulators. The new ICs for monitoring and control applications include the ADN8820 single-chip, continuous wave (CW) laser controller, the ADN2860 three-channel, non-volatile, digital potentiometer and the ADL5306 logarithmic converter for measuring optical power signal levels.
New Transmit and Receive ICs Enable Multi-Service Provisioning Platforms and Next Generation SONET Applications
The ADN2812 is a continuous tuning clock and data recovery IC for multi-service provisioning platforms. It can be designed into equipment today and accommodate changing bit rate requirements in the future. Featuring the exclusive data rate Read Back feature, it can lock onto any incoming data rate between 10 Mbps and 2.7 Gbps without the need for an external reference clock while providing the acquired data rate frequency through the I2C port. The ADN2812 is ideal for next generation protocol and data rate agnostic equipment that operate over Ethernet and SONET/SDH OC-1/3/12/48 and all associated FEC rates. The ADN2812 also is appropriate for MSPPs, WDM transponders, test equipment, backplanes, regenerators/repeaters, broadband cross-connects and routers.
The ADN2849 and ADN2859 are the only 10.7 Gbps external modulator drivers for continuous wave (CW) lasers that address the small size, low power, integration and performance requirements for high density systems. The ADN2849 provides a 3 V single-ended output to drive an electro-absorption modulator. The ADN2859 provides a 6 V peak-to-peak differential output to drive a differential Mach-Zehnder modulator. Both IC drivers feature a power dissipation of 900 mW (2 V swing, 1 V offset), which is typically one-third less than other solutions. Both devices are available in small 4 mm x 4 mm LFCSP packages, and as unpackaged die.
