1. Describe

The SN65LVDS1, SN65LVDS2, and SN65LVDT2DBVT devices are single, low-voltage, differential line drivers and receivers in small-outline transistor packages. The outputs are TIA/EIA-644 compliant and provide a minimum differential output voltage amplitude of 247 mV into a 100 Ω load at signaling rates up to 630 Mbps for drivers and 400 Mbps for receivers. When the SN65LVDS1 device is used in a point-to-point connection with an LVDS receiver , data or clock signals can be transmitted through printed circuit board traces or cables at very high rates with very low electromagnetic radiation and power consumption. Packaging, low power consumption, low EMI, high ESD tolerance and wide supply voltage range make this device ideal for battery powered applications. The SN65LVDS1, SN65LVDS2, and SN65LVDT2DBVT devices have an operating temperature range of –40°C to 85°C.
