DESCRIPTION
The
SN65LVDS122
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.
