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, 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 mux, 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.
