Overview
The SN65LVDS100DGKR is a high-speed differential translator/repeater from Texas Instruments, designed to handle signaling rates of up to 2 Gbps. This device is part of the SN65LVDx10x family, which includes receivers and drivers configured as repeaters. It accepts low-voltage differential signaling (LVDS), positive-emitter-coupled logic (PECL), or current-mode logic (CML) input signals and repeats them as either LVDS or PECL output signals. The device operates on a 3.3-V supply and is characterized for operation over a temperature range of –40°C to 85°C.
