DESCRIPTION
The SN75LVDS83A FlatLink™ transmitter contains four 7-bit parallel-load serial-out shift registers, a 7X clock
synthesizer, and five Low-Voltage Differential Signaling (LVDS) line drivers in a single integrated circuit. These
functions allow 28 bits of single-ended LVTTL data to be synchronously transmitted over five balanced-pair
conductors for receipt by a compatible receiver, such as the SN75LVDS82 and LCD panels with integrated LVDS
receiver.
When transmitting, data bits D0 through D27 are each loaded into registers upon the edge of the input clock
signal (CLKIN). The rising or falling edge of the clock can be selected via the clock select (CLKSEL) pin. The
frequency of CLKIN is multiplied seven times, and then used to unload the data registers in 7-bit slices and
serially. The four serial streams and a phase-locked clock (CLKOUT) are then output to LVDS output drivers.
The frequency of CLKOUT is the same as the input clock, CLKIN.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION (CONTINUED)
The SN75LVDS83A requires no external components and little or no control. The data bus appears the same at
the input to the transmitter and output of the receiver with the data transmission transparent to the user(s). The
only user intervention is selecting a clock rising edge by inputting a high level to CLKSEL or a falling edge with a
low-level input, and the possible use of the Shutdown/Clear (SHTDN). SHTDN is an active-low input to inhibit the
clock, and shut off the LVDS output drivers for lower power consumption. A low-level on this signal clears all
internal registers to a low-level.
The SN75LVDS83A is characterized for operation over ambient air temperatures of -10°C to 70°C.
Alternative device option: The SN75LVDS83B is an alternative to the SN75LVDS83A for clock frequency range
of 10MHz–135MHz. The SN75LVDS83B is available in a smaller BGA package in addition to the TSSOP
package.

APPLICATION INFORMATION
This section describes the power up sequence, provides information on device connectivity to various GPU and
LCD display panels, and offers a pcb routing example.
Power Up Sequence
The SN75LVDS83A does not require a specific power up sequence.
The user experience can be impacted by the way a system powers up and powers down an LCD screen. The
following sequence is recommended:
Power up sequence (SN75LVDS83A SHTDN input initially low):
1. Ramp up LCD power (maybe 0.5ms to 10ms) but keep backlight turned off.
2. Wait for additional 0-200ms to ensure display noise will not occur.
3. Enable video source output; start sending black video data.
4. Toggle LVDS83A shutdown to SHTDN = VIH
5. Send >1ms of black video data; this allows the LVDS83A to be phase locked, and the display to show
black data first.
6. Start sending true image data.
7. Enable backlight.
Power Down sequence (SN75LVDS83A SHTDN input initially high):
1. Disable LCD backlight; wait for the minimum time specified in the LCD data sheet for the backlight to go
low.
2. Video source output data switch from active video data to black image data (all visible pixel turn black);
drive this for >2 frame times.
3. Set SN75LVDS83A input SHTDN = GND; wait for 250ns.
4. Disable the video output of the video source.
5. Remove power from the LCD panel for lowest system power.
Signal Connectivity
While there is no formal industry standardized specification for the input interface of LVDS LCD panels, the
industry has aligned over the years on a certain data format (bit order). Figure 14 through Figure 17 show how
each signal should be connected from the graphic source through the SN75LVDS83A input, output and LVDS
LCD panel input. Detailed notes are provided with each figure.

Note A. FORMAT: The majority of 24-bit LCD display panels require the two LSBs of each color to be transferred
over the 4th serial data output Y3. Other 24-bit LCD display panels require the two LSB of each color to be
transmitted over the Y3 output. The system designer needs to verify which format is expected by checking the LCD
display data sheet.
•
Format 1: use with displays expecting the 2 MSB to be transmitted over the 4th data channel Y3. This is the
dominant data format in today's LCD panels
•
Format 2: use with displays expecting the 2 LSB to be transmitted over the 4th data channel.
Note B. Rpullup: install only to use rising edge triggered clocking.
Rpulldown: install only to use falling edge triggered clocking.
•
C1: decoupling cap for the VDDIO supply; install at least 1 × 0.1μF and 1 × 0.01μF
•
C2: decoupling cap for the VDD supply; install at least 1 × 0.1μF and 1 × 0.01μF.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
