DS90C185
Low Power 1.8V FPD-Link (LVDS) Serializer
General Description
Features
The DS90C185 is a Low Power Serializer for portable battery
powered applications that reduces the size of the RGB interface between the host GPU and the Display.
24 bit RGB plus three video control signals are serialized and
translated to LVDS compatible levels and sent as a 4 data +
clock (4D+C) reduced width LVDS compatible interface. The
LVDS Interface is compatible with FPD-Link (1) deserializers
and many LVDS based displays. These interfaces are commonly supported in LCD modules with “LVDS” or FPD-Link /
FlatLink single-pixel input interfaces.
Displays up to 1400 x 1050 @ 60 fps are supported with
24bpp in color depth. 18bpp may also be supported by a dedicated mode with a 3D+C output. Power Dissipation is minimized by the full LVCMOS design and 1.8V powered core and
VDDIO rails.
The DS90C185 is offered in the small 48 pin QFN package
and features single 1.8V supply operation for minimum power
dissipation (50mW typ).

PDB
DS90C185 converts a wide parallel LVCMOS input bus into
FPD-Link LVDS data. The device can be configured to support RGB-888 (24 bit color) or RGB-666 (18 bit color). The
DS90C185 has several power saving features including: selectable VOD, 18 bit / 24 bit mode select, and a power down
pin control.
In each input pixel clock cycle, data from D[27:0] is serialized
and driven out on TxOUT[3:0] +/- with TxCLKOUT +/-. If
18B_MODE is LOW, then TxOUT3 +/- is powered down and
the corresponding LVCMOS input signals are ignored.
The input pixel clock can range from 25 MHz to 105 MHz,
resulting in a total maximum payload of 700 Mbps (28 bits *
25MHz) to 2.94 Gbps (28 bits * 105 MHz). Each LVDS driver
will operate at a speed of 7 bits per input clock cycle, resulting
in a serial line rate of 175 Mbps to 735 Mbps. TxCLKOUT +/will operate at the same rate as CLK with a duty cycle ratio of
57:43.

18 bit / 24 bit Color Mode (18B)
The 18B pin can be used to further save power by powering
down the 4th LVDS driver in each used bank when the application requires only 18 bit color or 3D+C LVDS. Set the 18B
pin to logic HIGH to TRI-STATE® TxOUT3 +/-. For 24 bit color
applications this pin should be set to logic LOW. Note that the
power down function takes priority over the TRI-STATE®
function.

LVDS Outputs
The DS90C185's LVDS drivers are compatible with ANSI/
TIA/EIA-644–A LVDS receivers. The LVDS drivers an output
a power saving low VOD or a higher VOD to enable longer trace
and cable lengths by configuring the VODSEL pin.
Pixel Clock Edge Select (RFB)
The RFB pin determines the edge that the input LVCMOS
data is latched on. If RFB is HIGH, input data is latched on
the RISING EDGE of the pixel clock (CLK). If RFB is LOW,
the input data is latched on the FALLING EDGE of the pixel
clock. Note: This can be set independently of receiver’s output
clock strobe.

Power Management
The DS90C185 has several features to assist with managing
power consumption. The 18B_MODE pin allows the
DS90C185 to power down the unused LVDS driver for
RGB-666 (18 bit color) applications. If no clock is applied to
the CLK pin, the DS90C185 will enter a low power state. To
place the DS90C185 in its lowest power state, the device can
be powered down by driving the PDB pin to LOW.

LVCMOS Inputs
The DS90C185 has 28 data inputs. These inputs are typically
used for 24 or 18 bits of RGB video with 1, 2 or 3 video control
signal (HS, VS and DE) inputs and one spare bit that can be
used for L/R signaling or function as a general purpose bit. All
LVCMOS input pins are designed for 1.8V LVCMOS logic. All
LVCMOS inputs, including clock, data and configuration pins
have an internal pull down resistor to set a default state. If any
LVCMOS inputs are unused, they can be left as no connect
(NC) or connected to ground.
Sleep Mode (PDB)
The DS90C185 provides a power down feature. When the
device has been powered down, current draw through the
supply pins is minimized and the PLL is shut down. The LVDS
drivers are also powered down with their outputs pulled to
GND through 100Ω resistors.

Applications Information
and placement of external bypass capacitors less critical. This
practice is easier to implement in dense pcbs with many layers and may not be practical in simpler boards. External
bypass capacitors should include both RF ceramic and tantalum electrolytic types. RF capacitors may use values in the
range of 0.01 uF to 0.1 uF. Tantalum capacitors may be in the
2.2 uF to 10 uF range. Voltage rating of the tantalum capacitors should be at least 5X the power supply voltage being
used.
Surface mount capacitors are recommended due to their
smaller parasitics. When using multiple capacitors per supply
pin, locate the smaller value closer to the pin. It is recommended to connect power and ground pins directly to the
power and ground planes with bypass capacitors connected
to the plane with vias on both ends of the capacitor.
A small body size X7R chip capacitor, such as 0603, is recommended for external bypass. Its small body size reduces
the parasitic inductance of the capacitor. The user must pay
attention to the resonance frequency of these external bypass
capacitors, usually in the range of 20-30 MHz. To provide effective bypassing, multiple capacitors are often used to
achieve low impedance between the supply rails over the frequency of interest. At high frequency, it is also a common
practice to use two vias from power and ground pins to the
planes, reducing the impedance at high frequency.
Some devices provide separate power and ground pins for
different portions of the circuit. This is done to isolate switching noise effects between different sections of the circuit.
Separate planes on the PCB are typically not required. Pin
Description tables typically provide guidance on which circuit
blocks are connected to which power pin pairs. In some cases, an external filter many be used to provide clean power to
sensitive circuits such as PLLs.
Use at least a four layer board with a power and ground plane.
Locate LVCMOS signals away from the LVDS lines to prevent
coupling from the LVCMOS lines to the LVDS lines. Closely
coupled differential lines of 100 Ohms are typically recommended for LVDS interconnect. The closely coupled lines
help to ensure that coupled noise will appear as common
mode and thus is rejected by the receivers. The tightly coupled lines will also radiate less.
Information on the QFN (LLP) style package is provided in
Application Note: AN-1187.
Power Up Sequence
The VDD power supply pins do not require a specific power on
sequence and can be powered on in any order. However, the
PDB pin should only be set to logic HIGH once the power sent
to all supply pins is stable. Active clock and data inputs should
not be applied to the DS90C185 until all of the input power
pins have been powered on, settled to the recommended operating voltage and the PDB pin has be set to logic HIGH.
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 (DS90C185 PDB 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 won’t
occur.
3. Toggle DS90C185 power down pin to PDB = VIH.
4. Enable video source output; start sending black video
data.
5. Send >1ms of black video data; this allows the
DS90C185 to be phase locked, and the display to show
black data first.
6. Start sending true image data.
7. Enable backlight.
Power Down sequence (DS90C185 PDB 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 DS90C185 power down pin to PDB = GND.
4. Disable the video output of the video source.
5. Remove power from the LCD panel for lowest system
power.
Power Supply Filtering
The DS90C185 has several power supply pins at 1.8V. It is
important that these pins all be connected and properly bypassed. Bypassing should consist of at least one 0.1µF capacitor placed on each pin, with an additional 4.7µF – 22µF
capacitor placed on the PLL supply pin (VDDPLL). 0.01µF
capacitors are typically recommended for each pin. Additional
filtering including ferrite beads may be necessary for noisy
systems. It is recommended to place a 0 resistor at the bypass
capacitors that connect to each power pin to allow for additional filtering if needed. A large bulk capacitor is recommended at the point of power entry. This is typically in the 50µF —
100µF range.
LVDS Interconnect Guidlines
See AN-1108 and AN-905 for full details.
• Use 100Ω coupled differential pairs
• Use differential connectors when above 500Mbps
• Minimize skew within the pair
• Use the S/2S/3S rule in spacings
— S = space between the pairs
— 2S = space between pairs
— 3S = space to LVCMOS signals
• Place ground vias next to signal vias when changing
between layers
• When a signal changes reference planes, place a bypass
cap and vias between the new and old reference plane

Layout Guidelines
Circuit board layout and stack-up for the LVDS serializer devices should be designed to provide low-noise power feed to
the device. Good layout practice will also separate high frequency or high-level inputs and outputs to minimize unwanted
stray noise pickup, feedback and interference. Power system
performance may be greatly improved by using thin dielectrics (2 to 4 mils) for power / ground sandwiches. This
arrangement provides plane capacitance for the PCB power
system with low-inductance parasitics, which has proven especially effective at high frequencies, and makes the value
