Abstract: High Frequency Reference Design (HFRD) 19.2 is a fully functional transceiver targeted for the XFP multi-source agreement (MSA). The design showcases the Maxim MAX3991 receive clock/data recovery IC with integrated limiting amplifier, the MAX3992 transmit data retimer with equalizer, the MAX3975 DC coupled VCSEL driver and the Dallas DS1862 XFP Laser control/digital diagnostic IC. Data rates ranging from 9.95 to 10.7Gbps are supported in this reference design. Gerber files and schematics may be provided, however reference design boards are no longer available.
