DESCRIPTION
The DS90C383B transmitter converts 28 bits of
CMOS/TTL data into four LVDS (Low Voltage
Differential Signaling) data streams. A phase-locked
transmit clock is transmitted in parallel with the data
streams over a fifth LVDS link. Every cycle of the
transmit clock 28 bits of input data are sampled and
transmitted. At a transmit clock frequency of 65 MHz,
24 bits of RGB data and 3 bits of LCD timing and
control data (FPLINE, FPFRAME, DRDY) are
transmitted at a rate of 455 Mbps per LVDS data
channel. Using a 65 MHz clock, the data throughput
is 227 Mbytes/sec. The DS90C383B transmitter can
be programmed for Rising edge strobe or Falling
edge strobe through a dedicated pin. A Rising edge
or Falling edge strobe transmitter will interoperate
with a Falling edge strobe Receiver (DS90CF386)
without any translation logic.
"Input Clock Detection" feature will pull all
LVDS pairs to logic low when input clock is
missing and when /PD pin is logic high

APPLICATIONS INFORMATION
The DS90C383B are backward compatible with the DS90C383/DS90CF383, DS90C383A/DS90CF383A and are
a pin-for-pin replacement.
This device may also be used as a replacement for the DS90CF583 (5V, 65MHz) and DS90CF581 (5V, 40MHz)
FPD-Link Transmitters with certain considerations/modifications:
1. Change 5V power supply to 3.3V. Provide this supply to the VCC, LVDS VCC and PLL VCC of the transmitter.
2. The DS90C383B transmitter input and control inputs accept 3.3V LVTTL/LVCMOS levels. They are not 5V
tolerant.
3. To implement a falling edge device for the DS90C383B, the R_FB pin (pin 17) may be tied to ground OR left
unconnected (an internal pull-down resistor biases this pin low). Biasing this pin to Vcc implements a rising
edge device.
TRANSMITTER INPUT PINS
The TxIN and control input pins are compatible with LVCMOS and LVTTL levels. These pins are not 5V tolerant.
TRANSMITTER INPUT CLOCK/DATA SEQUENCING
The DS90C383B does not require any special requirement for sequencing of the input clock/data and PD
(PowerDown) signal. The DS90C383B offers a more robust input sequencing feature where the input clock/data
can be inserted after the release of the PD signal. In the case where the clock/data is stopped and reapplied,
such as changing video mode within Graphics Controller, it is not necessary to cycle the PD signal. However,
there are in certain cases where the PD may need to be asserted during these mode changes. In cases where
the source (Graphics Source) may be supplying an unstable clock or spurious noisy clock output to the LVDS
transmitter, the LVDS Transmitter may attempt to lock onto this unstable clock signal but is unable to do so due
the instability or quality of the clock source. The PD signal in these cases should then be asserted once a stable
clock is applied to the LVDS transmitter. Asserting the PWR DOWN pin will effectively place the device in reset
and disable the PLL, enabling the LVDS Transmitter into a power saving standby mode. However, it is still
generally a good practice to assert the PWR DOWN pin or reset the LVDS transmitter whenever the clock/data is
stopped and reapplied but it is not mandatory for the DS90C383B.
SPREAD SPECTRUM CLOCK SUPPORT
The DS90C383B can support Spread Spectrum Clocking signal type inputs. The DS90C383B outputs will
accurately track Spread Spectrum Clock/Data inputs with modulation frequencies of up to 100kHz (max.)with
either center spread of ±2.5% or down spread -5% deviations.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
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 as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
