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 SN65LVDT125A 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 SN65LVDS125A and SN65LVDT125A are characterized for operation from -40 °C to 85°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
