SLLS595A − OCTOBER 2003 − REVISED FEBRUARY 2004  
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.

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-termination resistors for  
those applications where board space is a premium.
