APPLICATIONS
DESCRIPTION
The TZA3000 optical receiver is a low-noise
transimpedance amplifier with AGC plus a limiting
amplifier designed to be used in SDH/SONET fibre optic
links. The TZA3000 amplifies the current generated by a
photo detector (PIN diode or avalanche photodiode) and
converts it to a differential output voltage.
PACKAGE
Digital fibre optic receiver in short, medium and long
haul optical telecommunications transmission systems
or in high speed data networks
Wideband RF gain block.
