Semtech GN1035
GN1035 2.5Gbps Transimpedance Amplifier with Automatic Gain Control
The Gennum® GN1035 is a fully integrated, silicon germanium transimpedance amplifier; providing wideband, low noise pre-amplification of signal current from a photodetector.
It features differential outputs, and incorporates an automatic gain control mechanism to increase dynamic range, allowing input signals up to 2.6mA peak. A decoupling capacitor on the supply is the only external circuitry required.
概览
功能
- Single +3.3V power supply
- Power dissipation 125mW (typ)
- Input noise current = 250nA rms when used with a 0.5pF detector
- Transimpedance gain 10kΩ into 100Ω load (differential)
- Bandwidth (-3dB) = 2.0GHz
- No photodiode bypass capacitor required in PIN-based applications.
- RSSI (received signal strength indicator) current output operates from sensitivity to overload, selectable source or sink
- Bondpad configuration, and output polarity control, allow for maximum flexibility in pin-out in a TO Can ROSA
- On-chip filter to improve sensitivity and control bandwidth
