DESCRIPTION
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-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. (Note: The ultimate
rate and distance of data transfer is dependent upon the
attenuation characteristics of the media, the noise coupling
to the environment, and other application specific
characteristics).
The SN65LVDS125 and SN65LVDT125 are characterized for
operation from –40°C to 85°C.
