Description

The TZA3044 is a high gain limiting amplifier that is designed to process signals from fibre optic preamplifiers like the TZA3043 and TZA3023. It is pin compatible with the NE/SA5224 and NE/SA5225 but with extended power supply range, and needs less external components.

Capable of operating up to 1.25 Gbits/s, the chip has input signal level detection with a user-programmable threshold.The data and level detection status outputs are differential outputs for optimum noise margin and ease of use.The TZA3044B has the same functionality as the TZA3044, but with TTL compatible status outputs (pins ST and STQ), and TTL compatible JAM input.
