3 Description

The SN65LVDS10x are a differential line receiver and

a LVTTL input (respectively) connected to four

differential line drivers that implement the electrical

characteristics of low-voltage differential signaling

(LVDS). LVDS, as specified in EIA/TIA-644 is a data

signaling technique that offers low-power, low-noise

coupling, and switching speeds to transmit data at

relatively long distances. (Note: The ultimate rate and

distance of data transfer is dependent upon the attenuation characteristics of the media, the noise

coupling to the environment, and other system

characteristics.)

The intended application of this device and signaling

technique is for point-to-point baseband data

transmission over controlled impedance media of

approximately 100 Ω. The transmission media may be printed-circuit board traces, backplanes, or cables.

Having the drivers integrated into the same substrate,

along with the low pulse skew of balanced signaling,

allows extremely precise timing alignment of the

signals repeated from the input. This is particularly

advantageous in distribution or expansion of signals

such as clock or serial data stream.

The SN65LVDS10x are characterized for operation from –40°C to 85°C.

The SN65LVDS10x are members of a family of LVDS

repeaters. A brief overview of the family is provided in the Selection Guide to LVDS Repeaters section.
