FDDI fiber optic postamplifier
Product specification
SA5224
DESCRIPTION
The SA5224 is a high-gain limiting amplifier that is designed to
process signals from fiber optic preamplifiers. Capable of operating
at 125Mb/s, the chip is FDDI compatible and 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 SA5225 which is an ECL 10K
version of the SA5224.
FEATURES
• Wideband operation: 1.0kHz to 120MHz typical
• Applicable in 155Mb/s OC3/SONET receivers
• Operation with single +5V or –5.2V supply
• Differential 100k ECL outputs
• Programmable input signal level-detection
• Fully differential for excellent PSRR to 1GHz
