3 Description

The SN65LVDS1, SN65LVDS2, and SN65LVDT2 devices are single, low-voltage, differential line drivers and receivers in the small-outline transistor package. The outputs comply with the TIA/EIA-644 standard and provide a minimum differential output voltage magnitude 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 with an LVDS receiver (such as the SN65LVDT2) in a point-to-point connection, data or clocking signals can be transmitted over printed-circuit board traces or cables at very high rates with very low electromagnetic emissions and power consumption. The packaging, low power, low EMI, high ESD tolerance, and wide supply voltage range make the device ideal for battery-powered applications.

The SN65LVDS1, SN65LVDS2, and SN65LVDT2 devices are characterized for operation from –40°C to 85°C.
