DESCRIPTION\nThe 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.FEATURES\n• Wide dynamic input range from 1 µA to 1.5 mA\n• Low equivalent input noise of 3.5 pA/√Hz (typical)\n• Differential transimpedance of 21 kΩ\n• Wide bandwidth from DC to 600 MHz\n• Differential outputs\n• On-chip Automatic Gain Control (AGC)\n• No external components required\n• Single supply voltage from 3.0 to 5.5 V\n• Bias voltage for PIN diode\n• Pin compatible with SA5223.APPLICATIONS\n• Digital fibre optic receiver in short, medium and long haul optical telecommunications transmission systems or in high-speed data networks\n• Wideband RF gain block.
