SLLS416B – JUNE 2000 – REVISED DECEMBER 2003

LVDS QUAD DIFFERENTIAL LINE DRIVER

The SN65LVDS047 is characterized for operation

from -40°C to 85°C.

• >400 Mbps (200 MHz) Signaling Rates

• Flow-Through Pinout Simplifies PCB Layout

• 300 ps Maximum Differential Skew

• Propagation Delay Times 1.8 ns (Typical)

• 3.3 V Power Supply Design

• ±350 mV Differential Signaling

• High Impedance on LVDS Outputs on Power

Down

• Conforms to TIA/EIA-644 LVDS Standard

• Industrial Operating Temperature Range

(-40°C to 85°C)

• Available in SOIC and TSSOP Packages

The SN65LVDS047 is a quad differential linedriver

that implements the electrical characteristics of

low-voltage differential signaling (LVDS). This

signaling technique lowers the output voltage levels

of 5-V differential standard levels (such as

EIA/TIA-422B) to reduce the power, increase the

switching speeds, and allow operation with a 3.3-V

supply rail. Any of the four current-mode drivers will

deliver a minimum differential output voltage

magnitude of 247 mV into a 100- Ω load when

enabled.

The intended application of this device and signaling

technique is for point-to-point and multi-drop

baseband data transmission over controlled

impedance media of approximately 100 Ω . The

transmission media may be printed-circuit board

traces, backplanes, or cables. 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.
