Abstract: High-Frequency Reference Design (HFRD)-30.1 is a high-speed Small Form Factor Pluggable (SFP+) host board designed for evaluating SFP and SFP+ modules operating at data rates up to 12Gbps. The host board can be used to test a variety of difference modules, and includes additional features for testing, monitoring, and programming Maxim SFP+ reference design boards. HFRD-30.1 provides micro-strip transmission lines and SMA connectors for transmitted data and received data. Supply current monitors, voltage monitors, and digital I/O control/monitoring are provided through the graphical user interface. Signal connections from the host board to the module board are made through a 20-pin SFP connector.
