SA5224

INTEGRATED CIRCUITS SA5224 FDDI fiber optic postamplifier Product specification Replaces datasheet NE/SA5224 of 1995 Apr 26 IC19 Data Handbook 1998 Oct 07 Philips Semiconductors Philips Semiconductors Product specification FDDI fiber optic postamplifier 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.
