M02129中文资料8.5 Gbps Transimpedance Amplifier with AGC数据手册MACOM规格书

描述 Description

8.5 Gbps Limiting Transimpedance Amplifier with rate selectable 1 G operation The M02129 is a 8.5 Gbps TIA achieving a wide input dynamic range to support different transmission distance requirements. Input overload of 1.5 mAPP (4 mAPP without damage) supports an input sensitivity of better than -17.5 dBm is useful for single-mode, high power long haul links, as well as short haul multi-mode links. In order to satisfy such high sensitivity and good optical overload requirements, automatic gain control (AGC) is implemented in the M02129. The AGC monitors the output amplitude and automatically reduces the TIA gain when the photodiode current exceeds the AGC threshold, maintaining the output at a constant level. A replica of the average photodiode current is available at the MON pad for photo-alignment and 'Loss of Signal' detecting.8.5 Gbps Limiting Transimpedance Amplifier with rate selectable 1 G operation The M02129 is a 8.5 Gbps TIA achieving a wide input dynamic range to support different transmission distance requirements.
