Philips Semiconductors
SDH/SONET STM4/OC12 optical receiver
Objective specification
TZA3000
FEATURES
• Low equivalent input noise, typically 3.5 pA/√Hz
• Wide dynamic range, typically 1 µA to 1.5 mA
• On-chip low-pass filter. The bandwidth can be varied
between 370 and 600 MHz using an external resistor.
Default value is 470 MHz.
• Differential transimpedance of 1.8 MΩ
• On-chip AGC (Automatic Gain Control)
• PECL (Positive Emitter-Coupled Logic) or CML
(Current-Mode Logic) 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.
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.
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.
