TZA3000 is an SDH/SONET STM4/OC12 optical receiver with features such as low equivalent input noise, wide dynamic range, on-chip low-pass filter, differential transimpedance, automatic gain control, data output compatibility, LOS detection, etc.
The Philips TZA3000 is an integrated circuit designed as a low-noise transimpedance amplifier with Automatic Gain Control (AGC) and a limiting amplifier. It is specifically engineered for use in SDH/SONET fibre optic transmission systems and high-speed data networks, amplifying current from PIN or avalanche photodiodes into differential output voltages.
The device features a wide dynamic range of typically 1 pA to 1.5 mA and includes an on-chip low-pass filter with adjustable bandwidth between 370 and 600 MHz. It offers both PECL and CML compatible data outputs, along with Loss-Of-Signal (LOS) detection capabilities.
| Dynamic Range | typically 1 pA to 1.5 mA |
|---|---|
| Bandwidth | 370 to 600 MHz (default 470 MHz) |
| Transimpedance | 1.8 MΩ |
| Supply Voltage | 3.0 to 5.5 V |
| Input Noise | typically 3.5 pA/VHz |
The default value for the bandwidth is 470 MHz.
The device supports both PECL (Positive Emitter-Coupled Logic) and CML (Current-Mode Logic) compatible data outputs.
It is designed for use in SDH/SONET fibre optic links, short to long haul optical telecommunications transmission systems, and high speed data networks.
