M02139数据手册MACOM中文资料规格书

描述 Description

The M02139 is a multi-rate TIA supporting data rates from 1 Gbps to 10.3 Gbps and having a wide input dynamic range to support different transmission distance requirements. Input overload of 2 mAPP and input sensitivity of better than -19 dBm are 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 M02139. 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. Requiring no extra pins on the ROSA, rate select is controlled by the DC potential on the MON pad. Low rate is optimized for 1 Gbps/1.25 Gbps performance with a typical sensitivity lower than -22 dBm. A replica of the average photodiode current is available at the MON pad for photo-alignment and SFF-8472 Rx power monitoring.
