Semtech’s GN1052CWA2 is a fully integrated silicon germanium BiCMOS transimpedance amplifier, providing wideband, low noise preamplification of signal current from a PIN photodiode or APD. It features differential outputs. A decoupling capacitor on the supply is the only external component required.
功能
- Single +3.3V power supply
- 功耗：180 mW（典型值）
- Input Noise Density 10pA/√Hz
- Input noise current = 1 μA rms when used with a 0.2pF detector and 1nH input bond wire
- Transimpedance gain = 4kΩ into a 100Ω load (differential)
- Input current overload = 2.6mA pk (+1.1dBm for 1A/W responsivity - meets 10 Gigabit Ethernet specification)
- Upper Bandwidth (-3dB) = 13GHz
- Lower Bandwidth (-3dB) = 24kHz
- Operates at OC-192/STM-64 up to 11.3Gbps NRZ rates
- Power supply rejection at 100kHz = 16dB
- 针对 PIN 型光电二极管进行优化
- Can be used with APD (0.4pF) at 10Gbps
- RSSI（接收信号强度指示），电流输出 operates from sensitivity to overload
- Constant photodiode reverse bias voltage = 2V (anode to input, cathode to VCC)
- Minimal external components, supply decoupling only
- Operating junction temperature range = -40 to +125°C
应用
- SONET/SDH-based transmission systems, test equipment and modules
- OC-192 fibre optic modules and line termination
- 10 Gigabit Ethernet
- 光纤通道
- Serial data systems up to 11.3Gbps
