GN1052CWA2
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
- 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

在 2018 年进行了大量演示和 alpha 模块测试之后，双密度版本的四通道小型可插拔 (QFSP) 多源协议 (MSA) 模块标准有望成为新线卡的规则。QSFP-DD 热潮的隐含意义不是模块本身的物理特性，而是转向先进信令方法的趋势。十年前，QSFP28 的问世预示着使用 NRZ 信令的 25Gbps 电通道即将占据主导地位。如今，QSFP-DD 及其更庞大的表亲 —— 八进制 SFP 或 OSFP ，都使用 PAM4 信令。其用得最多的是 50Gbps 通道。但 QSFP-DD 足够灵活，可以在各种实施中使用八通道接口：25G x 8 用于 200Gbit 以太网，50G x 8 用于 400Gbit 以太网，可能还有一些早期的 100G x 8 用于预标准 800Gbit 以太网。
