DESCRIPTION

The SA5225 is a high-gain limiting amplifier that is designed to process signals from fiber optic preamplifiers. Capable of operating at 125Mb/s, the chip has input signal level-detection with a user-adjustable threshold. The DATA and LEVEL-DETECT outputs are differential for optimum noise margin and ease of use. Also available is the SA5224 which is optimized for FDDI applications.

FEATURES

• Wideband operation: 1.0kHz to 120MHz typical

• Applicable in 155Mb/s OC3/SONET receivers

• Operation with single +5V or –5.2V supply

• Differential 10k ECL outputs

• Programmable input signal level-detection

• Fully differential for excellent PSRR to 1GHz

APPLICATIONS

• Data communication in noisy industrial environments

• LANs
