General Description

The GTLP17T616 is a 17-bit registered bus transceiver that provides LVTTL to GTLP signal level translation. It allows for transparent, latched and clocked modes of data flow and provides a buffered GTLP (CLKOUT) clock output from the LVTTL CLKAB. The device provides a high speed interface between cards operating at LVTTL logic levels and a backplane operating at GTLP logic levels. High speed backplane operation is a direct result of GTLP’s reduced output swing (
