SN65LVDT125ADBTRG4

LVDS 4×4交叉点开关 LVDS 4x4 CROSSPOINT SWITCH

DESCRIPON

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