The signlaing rate of a line is the number of voltage
transitions that are made per second expressed in the units
bps (bits per second).
The SN65LVDS122 and SN65LVDT122 are
crosspoint switches that use low voltage differential
signaling (LVDS) to achieve signaling rates as high
as 1.5 Gbps. They are pin-compatible speed upgrades to the SN65LVDS22 and SN65LVDM22. The
internal signal paths maintain differential signaling for
high speeds and low signal skews. These devices
have a 0-V to 4-V common-mode input range that
accepts LVDS, LVPECL, or CML inputs. Two logic
pins (S0 and S1) set the internal configuration between the differential inputs and outputs. This allows
the flexibility to perform the following configurations:
2 x 2 crosspoint switch, 2:1 input multiplexer, 1:2
splitter or dual repeater/translator within a single
device. Additionally, SN65LVDT122 incorporates a
110-Ω termination resistor for those applications
where board space is a premium. Although these
devices are designed for 1.5 Gbps, some applications
at a 2-Gbps data rate can be supported depending on
loading and signal quality.
The intended application of this device is ideal for
loopback switching for diagnostic routines, fanout
buffering of clock/data distribution provide protection
in fault-tolerant systems, clock multiplexing in optical
modules, and for overall signal boosting over
extended distances.
The SN65LVDS122 and SN65LVDT122
characterized for operation from –40°C to 85°C.

All typical values are at 25°C and with a 3.3-V supply.
tsk(p) is the magnitude of the time difference between the tPLH and tPHL of any output of a single device.
tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices
operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
Jitter is specified by design and characterization. Stimulus jitter has been subtracted.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
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.
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.
