APPLICATIONS
GENERAL DESCRIPTION
The TZA3044 is a high gain limiting amplifier that is
designed to process signals from fibre optic preamplifiers
like the TZA3043. 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 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.
