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-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.
