ORDERING INFORMATION TYPE NUMBER TZA3023T TZA3023U BLOCK DIAGRAM PACKAGE NAME SO8 − DESCRIPTION plastic small outline package; 8 leads; body width 3.9 mm bare die in waffle pack carriers; die dimensions 1.030 × 1.300 mm APPLICATIONS TZA3023 Digital fibre optic receiver in short, medium and long haul optical telecommunications transmission systems or in high-speed data networks Wideband RF gain block. DESCRIPTION The TZA3023 is a low-noise transimpedance amplifier with AGC designed to be used in STM4/OC12 fibre optic links. It amplifies the current generated by a photo detector (PIN diode or avalanche photodiode) and converts it to a differential output voltage.
