DESCRIPTION

The LX5255 is a Low Voltage Differential (LVD) terminator designed to comply with the LVD termination specification in the SPI-4 document. The LX5255 is specifically designed for LVD only applications. Because the LX5255 supports only LVD, it has lower output capacitance than multimode terminators such as the LX5250.
