3 Description

The SN65LVDTxx devices are multi-channel LVDS

transceivers that operate using LVDS line drivers and

receivers. The SN65LVDTxx devices support

signaling rates of at least 250 Mbps, and the devices

operate from a single supply (typically at 3.3 V) in a

20-pin TSSOP package designed for easy PCB

layout.

The SN65LVDT14 and SN65LVDT41 provide

general-purpose, asymmetric, bidirectional

communication with the added benefit of high noise

immunity, low electromagnetic interference (EMI),

and increased cable length through the use of LVDS

lines. The SN65LVDT14 and SN65LVDT41 are

primarily used for SPI over LVDS applications.

The SN65LVDT14 combines one LVDS line driver

with four terminated LVDS line receivers in one

package. The SN65LVDT14 can be used to extend

asymmetric, bidirectional interfaces such as SPI over

long distances, and should be located at the SPI

slave.

The SN65LVDT41 combines four LVDS line drivers

with a single terminated LVDS line receiver in one

package. The SN65LVDT41 can be used to extend

asymmetric, bidirectional interfaces such as SPI over

long distances, and should be located at the SPI

master.
