Overview
INTEGRATED CIRCUITS DATA SHEET TZA3030 SDH/SONET STM1/OC3 optical receiver Objective specification File under Integrated Circuits, IC19 1998 Aug 24 Philips Semiconductors Objective specification SDH/SONET STM1/OC3 optical receiver FEATURES • Low equivalent input noise, typically 1 pA/√Hz • Wide dynamic range, typically 0.
5 µA to 2 mA • On-chip low-pass filter.
The bandwidth can be varied between 90 and 150 MHz using an external resistor.
Default value is 120 MHz.
• Differential transimpedance of 1.
8 MΩ • On-chip Automatic Gain Control (AGC) • Positive Emitter Coupled Logic (PECL) or Current-Mode Logic (CML) compatible data outputs • LOS (Loss Of Signal) detection • LOS threshold level can be adjusted using a single external resistor • On-chip DC offset compensation • Single supply voltage from 3.
0 to 5.
5 V • Bias voltage for PIN diode.
ORDERING INFORMATION TYPE NUMBER TZA3030HL TZA3030U PACKAGE NAME LQFP32 − DESCRIPTION plastic low profile quad flat package; 32 leads; body 5 × 5 × 1.
4 mm naked die in waffle pack carriers; die dimensions 1.
58 × 1.
58 mm APPLICATIONS TZA3030 • 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 TZA3030 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 TZA3030 amplifies the current generated by a photo detector (PIN diode or avalanche photodiode) and converts it to a differential output voltage.
