Objective specication
SDH/SONET STM1/OC3 transimpedance amplier
TZA3033
FEATURES
Low equivalent input noise, typically 1 pA/√Hz
Wide dynamic range, typically 0.25 A to 1.6 mA
Differential transimpedance of 117 k
Bandwidth minimum 150 MHz
Differential outputs
On-chip AGC (Automatic Gain Control)
No external components required
Single supply voltage from 3.0 to 5.5 V
Bias voltage for PIN diode
Pin compatible with SA5223.
APPLICATIONS
Digital fibre optic receiver in short, medium and long
haul optical telecommunications transmission systems
or in high speed data networks
Wideband RF gain block.
GENERAL DESCRIPTION
The TZA3033 is a low-noise transimpedance amplifier with
AGC designed to be used in STM1/OC3 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.
