MG3650   is a dual rate burst mode transimpedance amplifier (TIA) with reset and data rate selection. When the part is operating in burst mode, its typical bandwidth (or data rate) can be changed between 9GHz (10Gbps) and 3GHz (2.5Gbps) with external rate select signal. With an appropriate APD detector, its optical sensitivity can be as high as -25dBm (10Gb/s BER 10-12) and its overload tolerance can be greater than 2mApp.

Limiting Amplifiers

Mignal offers unique multi-mode limiting amplifiers optimized for direct coupling between TIA output and LA. In burst mode GPON and EPON OLT applications, this coupling scheme greatly reduces extra components on PCB resulting in advantageous benefits for module vendors: big reduction in module BOM, board space saving, enhanced reliability, and minimized coupling loss etc.
