TZA3000
TZA3000 is SDH/SONET STM4/OC12 optical receiver manufactured by NXP Semiconductors.
FEATURES
- Low equivalent input noise, typically 3.5 p A/√Hz
- Wide dynamic range, typically 1 µA to 1.5 m A
- 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) patible data outputs
- LOS (Loss-Of-Signal) detection
- LOS threshold level can be adjusted using a single external resistor
- On-chip DC offset pensation
- Single supply voltage from 3.0 to 5.5 V
- Bias voltage for PIN diode. ORDERING INFORMATION TYPE NUMBER TZA3000HL TZA3000U PACKAGE NAME LQFP32 naked die DESCRIPTION plastic low profile quad flat package; 32 leads; body 5 × 5 × 1.4 mm die in waffle pack carriers; die dimensions 1.58 × 1.58 mm APPLICATIONS
- Digital fibre optic receiver in short, medium and long haul optical telemunications 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.
