TZA3034
Information as of 2000-08-17
TZA3034; SDH/SONET STM1/OC3 postamplifier
The TZA3034 is a high gain limiting amplifier that is designed to process signals from fibre optic preamplifiers like the TZA3033. 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 at 155 Mbits/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.
