The SN65LVDS125 and SN65LVDT125 are 4x4 nonblocking crosspoint switches. Low-voltage differential signaling (LVDS) is used to achieve signaling rates of 1.5 Gbps per channel. Each output driver includes a 4:1 multiplexer to allow any input to be routed to any output. Internal signal paths are fully differential to achieve the high signaling speeds while maintaining low signal skews. The SN65LVDT125 incorporates 110-Ωtermination resistors for those applications where board space is a premium.
