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. 175 mV/div DESCRIPTION VIC = 1.2 V SVIDS = 200 mV 1.5 Gbps 223−1 PRBS VCC = 3.3 V 200 − ps/div 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. !" #!$% &"' &! #" #" (" " " !" && )*' &! #"+ &" ""%* %!&" "+ %% #""' Copyright 2003 − 2004, Texas Instruments Incorporated www.ti.com SLLS595A − OCTOBER 2003 − REVISED FEBRUARY 2004 These devices have limited built-in ESD protection.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
