The dual channels incorporate wide common-mode (0 V to 4 V) receivers, allowing for the receipt of LVDS, LVPECL, and CML signals. The dual outputs are LVPECL drivers to provide high-speed operation. The SN65LVCP23 provides a single device supporting 2:2 buffering (repeating), 1:2 splitting, 2:1 multiplexing, 2x2 switching, and LVDS/CML to LVPECL level translation on each channel. The flexible operation of the SN65LVCP23 provides a single device to support the redundant serial bus transmission needs (working and protection sw...
