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.
