PHY1075-01 Matching Circuits for 4G TOSA

Abstract: The Phyworks PHY1075 is a combined laser driver and limiting amplifier for use within SFF optic modules for applications that have a data rate of up to 4.25Gbps. To achieve the best Tx optical performance at 4.25Gbps, the matching network between PHY1075 and the transmitter optical subassembly (TOSA) needs to be carefully designed and optimized. This application note describes the recommended Tx-matching network for a 4.25Gbps application.
