Use of the PHY1040 IC for 125Mbps to 2.125 Gbps SFP Applications

Abstract: The Phyworks PHY1040 is a VCSEL/laser driver and limiting amplifier for high-performance, low-cost optical transceivers. With a carefully designed matching circuit, the PHY1040 supports applications of up to 2.125Gbps. This application note describes the principles of the PHY1040 small form-factor pluggable (SFP) reference design and explains how to reduce development time.
