SA5225

INTEGRATED CIRCUITS SA5225 Fiber optic postamplifier Product specification Replaces datasheet NE/SA5225 of 1997 Jun 05 IC19 Data Handbook 1998 Oct 07 Philips Semiconductors Philips Semiconductors Product specification Fiber optic postamplifier SA5225 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.
