GENERAL 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.
FEATURES
• Pin compatible with the NE/SA5224 and NE/SA5225 but with extended power supply range and less external component count
• Wideband operation from 1.0 kHz to 1.25 GHz typical
• Applicable in 622 Mbits/s SDH/SONET receivers and 1.25 Gbits/s Gigabit Ethernet receivers
• Single supply voltage from 3.0 to 5.5 V
• Positive Emitter Coupled Logic (PECL) compatible data outputs
• Positive Emitter Coupled Logic (PECL) compatible status outputs (TTL compatible status outputs for the TZA3044B)
• Programmable input signal level detection to be adjusted using a single external resistor
• On-chip DC offset compensation without external capacitor.
APPLICATIONS
• Digital fibre optic receiver for SDH/SONET STM4/OC12 and Gigabit Ethernet applications
• Wideband RF gain block.
