description
This family of four, eight, and sixteen differential
line drivers implements the electrical characteris-
tics of low-voltage differential signaling (LVDS).
Thissignalingtechniquelowerstheoutputvoltage
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 sixteen current-mode
drivers will deliver a minimum differential output
voltage magnitude of 247 mV into a 100-Ω load
when enabled.

Theintendedapplicationofthisdeviceandsignalingtechniqueisforpoint-to-pointandmultidropbasebanddata
transmission over controlled impedance media of approximately 100 Ω. The transmission media can be
printed-circuit board traces, backplanes, or cables. The large number of drivers integrated into the same
substrate, along with the low pulse skew of balanced signaling, allows extremely precise timing alignment of
clock and data for synchronous parallel data transfers. When used with the companion 16- or 8-channel
receivers, the SN65LVDS386 or SN65LVDS388, over 300 million data transfers per second in single-edge
clocked systems are possible with very little power. (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.)
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

description (continued)
When disabled, the driver outputs are high impedance. Each driver input (A) and enable (EN) have an internal
pulldown that will drive the input to a low level when open circuited.
The SN65LVDS387, SN65LVDS389, and SN65LVDS391 are characterized for operation from –40°C to 85°C.
The SN75LVDS387, SN75LVDS389, and SN75LVDS391 are characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Signaling Rate vs Distance
The ultimate data transfer rate over a given cable or trace length involves many variables. Starting with the
capabilities of this LVDS driver to reproduce a data pulse as short as 1.6 ns (a 630 Mbps signaling rate) with
less than 500 ps of pulse distortion, any degradation of this pulse by the transmission media will necessarily
reduce the timing margin at the receiving end of the data link.
The timing uncertainty induced by the transmission media is commonly referred to as jitter and comes from
numerous sources. The characteristics of a particular transmission media can be quantified by using an
eyepattern measurement such as shown in Figure 12, which shows about 340 ps of jitter or 20% of the data
pulse width.

Figure 15. Typical LVDS Eyepattern
A generally accepted range of jitter at the receiver inputs that allows data recovery is 5% to 20% of the unit
interval (data pulse width). Table 1 shows the signaling rate achieved on various cables and lengths at a 5%
eyepattern jitter with a typical LVDS driver.

Cable A: CAT 3, specified up to 16 MHz, no shield, outside conductor diameter ( ) 0.52 mm
Cable B: CAT 5, specified up to 100 MHz, no shield, 0.52 mm
Cable C: CAT 5, specified up to 100 MHz, taped over all shield, 0.52 mm
Cable D: CAT 5 (exceeding CAT 5), specified up to 300 MHz, braided over all shield plus taped individual shield for any
pair, 0.64 mm (AWG22)
Cable E: CAT 5 (exceeding CAT 5), specified up to 350 MHz, 0.64 mm (AWG22), no shield
Cable F: CAT 5 (exceeding CAT 5), specified up to 350 MHz, “self-shielded”, 0.64 mm (AWG22)
During synchronous parallel transfers, skew between the data and clock lines will also reduce the timing margin.
This must be accounted for in the system timing budget. Fortunately, the low output skew of this LVDS driver
will generally be a small portion of this budget.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
