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.
