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-Ω termination resistors for those applications where board space is a premium. Designed to support signaling rates up to 1.5 Gbps for OC-12 clocks (622 MHz). The 1.5-Gbps signaling rate allows use in HDTV systems, including SMPTE 292 video applications requiring signaling rates of 1.485 Gbps. The SN65LVDS125 and SN65LVDT125 are characterized for operation from - 40°C to 85°C.
