DESCRIPTION
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 up-
grades 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 be-
tween 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-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 are
characterized for operation from –40°C to 85°C.

These devices have limited built-in ESD protection. The leads should be shorted together or the device
placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
