Product Description

The PI90LVB179, PI90LVB180, PI90LVB050, and PI90LVB051 are differential line drivers and receivers (transceivers) that are similar to the IEEE 1596.3 SCI and ANSI/TIA/EIA-644 LVDS standards (the difference is that the driver output current is doubled). This modification enables true half-duplex operation with more than one LVDS driver or with two line transmission resistors over a 50 ohm differential transmission line. These devices use low-voltage differential signaling (LVDS) to achieve data rates in excess of 660 Mbps while being less susceptible to noise than single-ended transmission.
