TZA3019 Overview
The TZA3019 is a low gain postamplifier multiplexer with a dual RSSI and/or LOS detector that is designed for use in critical signal path control applications, such as loop-through, redundant channel switching or Wavelength Division Multiplexing (WDM). The signal path is unregistered, so no clock is required for the data inputs. The signal path is fully differential and delay matched.
TZA3019 Key Features
- Dual postamplifier
- Single 3.3 V power supply
- Wideband operation from 50 kHz to 2.5 GHz (typical value)
- Fully differential
- Channels are delay matched
- On-chip DC-offset pensations without external capacitor
- Interfacing with positive or negative supplied logic
- Switching possibility between channels
- Positive Emitter Coupled Logic (PECL) or Current-Mode Logic (CML) patible data outputs adjustable from 200 to 800 mV (p-
- Power-down capability for unused outputs and detectors
TZA3019 Applications
- Postamplifier for Synchronous Digital Hierarchy and Synchronous Optical Network (SDH/SONET) transponder
