DESCRIPTION
The SN65LVDS125A and SN65LVDT125A 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 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.
