L5-A Low-to-Mid End LCD-TV BOARD OVERVIEW
L5-A Low-to-Mid End LCD TV board incorporates the LCD Controller gm2221, to create a
high quality, stand-alone LCD-based TV system for consumer applications. Figure 1
illustrates the Block diagram of the board.
This board supposed to have two versions:
1. Low-End (to drive 14''-15’’ 4:3 panels)
2. Mid-End (to drive 17’’-20’’ 4:3 and 17’’-22’’-23'' 16:9 panels)
Figure 1 System Block Diagram
L5-A board supports 5 types of video and graphics inputs. These inputs are: Analog
terrestrial tuner input for multisystem PAL/SECAM transmission, SCART input (x2), S-VHS
input, RCA input and analog PC video input.
The analog RGB signals coming from the PC input (via D-Sub15 connector P401) are
directly connected to the gm2221 analog input port.
One EDID IC (U400) is provided on board to support VESA standard plug-and play
compatibility.

On the board, one high quality video decoder (U100) is provided (VPC3230D of Micronas)
to process video inputs coming from the video sources. The video processor can process 3
composite video inputs and 1 S-Cideo input from the NTSC/PAL video sources. The CVBS
output recovered from the tuner module is made available to one of the video inputs of the
video decoder.
The digitized video output (in ITU-656 format) from U100 is fed to the dedicated video Port
of gm2221 for decoding and processing.
Gm2221 makes it possible to perform scaling and de-interlacing for the video input.
A 4Mbit serial flash ROM (U503) is used for storing system firmware. Also the footprint for
a parallel flash ROM, which can be upto 2Mbits, is available on the board. This option can
be used either for development or for production purposes.
The gm2221 provides direct connect via the integrated LVDS transmitters to LCD panels
with integrated LVDS receivers. Both single LVDS (via S503) and double LVDS(via S502)
panels can be supported directly from the L5-A main-board. For single LVDS panels, only
S503 connector is soldered on the main-board, which is a 20 pin connector. For Double
LVDS panels, only S502 connector is soldered on the main-board, which is a 30 pin
connector. For supporting different LVDS panels, different LVDS cables (either single or
double LVDS) can be made used.
For supporting different single or double TTL panels, a daughter board interface is used via
40 pin S506 connector. On this connector, the signals are 3x8bit RGB with TTL control
signals (i.e. HSync, VSync, CLK, O/E etc.) to support a wide variety of LCD panels.
Depending on the panel used, different daughter boards will be used to support that
particular panel. For single TTL panels, the daughter board will just be a routing the RGB
and control signals to the particular connector interface for that particular panel. For double
TTL panels, there will be two LVDS receiver IC’s on the daughter board (double TTL is not
directly from GM2221 but double LVDS is supporter due to IC packaging problems) to
demodulate double LVDS signal into double TTL signal.
The LCD panel resolution supported can be up to SXGA at 75 Hz or UXGA at 60 Hz.
It is important to note that at any point in time gm2221 could drive only one type of Panel.
When LVDS Panel is connected (to connector S503 or S502) ensure that the panel
backlight is connected to S508. The integrated PWM output from gm2221 is used to
control the LCD panel backlight intensity for dimming functions.
The on screen display is implemented using OSD capability of gm2221. Infra Remote (IR)
controller connector (S507) is provided as a primary control interface for connecting IR
detector to the GPIO of gm2221. An IR remote controller unit and detector provide remote
OSD menu access at user convenience.

A keypad connector (S507) is provided which utilizes the integrated low bandwidth ADC in
gm2221 for scanning 5-6 keys (menu,V+,V-,P+,P- keys standard- source key optional) on
the keypad. The keypad allows access to the OSD without using the remote IR controller.
The L5-A board also has In System Programming (ISP) capability for the external flash
ROM using DDC2Bi. This can be done using the D-Sub 15 (PC) connector on the board.
ISP can also be performed using G-probe through the RS232 interface.
One channel of the dual channel FET power switch (U602) is used to control the power
sequencing to the LCD panel. Depending on the type of the panel, the input voltage to this
FET device can be chosen as shown below:
For +3.3V panels J601 is soldered on the main-board
For +5V panels J600 is soldered on the main-board
For +12V panels J603 is soldered on the main-board
An LM2576, a step-down regulator IC (U600), is used to generate the main +5V_STBY
voltage on the board. This IC can deliver up-to 3 Ampers of 5Volts. There is no stand-by
control for this regulator, which means this IC is always on, as soon as power is supplied
to the board.
U603(+3.3V_STBY) and U605 (+1.8V_STBY) linear regulators are used to supply the
voltage necessary for the GM2221 IC and some peripherals. These voltages are also
available in stand-by mode to power the microprocessor inside gm2221, LED, IR receiver
IC and EEPROM. These devices are necessary to wake up the board from stand-by state.
Second channel of the dual channel FET power switch (U602) is used to control cut some
voltages in stand-by mode. These voltages are +5V, +3.3V and +2.5V. These voltages are
used by the video processor (VPC 3230D), audio processor (MSP 34x0G), teletext
processor (SDA5550), tuner and some peripheral IC’s and circuitry. In order to limit the
stand-by power consumption, these voltages are not available in stand-by mode. Also the
audio amplifier (TDA1517) is also in its stand-by mode using its dedicated stand-by pin.
The board employs MSP3410G, a multi-system audio processor solution from Micronas.
The system supports 4 audio input ports, one of which is not used on the L5-A board.
Audio output is provided with speaker and headphone jacks (S409, S401) provided on the
board. The sound IF signal from the tuner is connected to the audio processor directly.

4. GM2221 LCD TV CONTROLLER
The gm2221 IC is a highly integrated single channel scaler that can be used for both LCD
monitors up to SXGA/UXGA resolutions and rear projection systems with DLP and HTPS
LCD engines up to 1280x720 (720P). Some of the key features include:
•Single processing channel.
•RGB and YUV signal processing with RGB to YUV and YUV to RGB color space
converters.
•Video signal processing/de-interlacing using spatial, VT (vertical-temporal) diagonal
interpolation.
•The on-chip turbo x86 micro-controller is used as the system CPU.
•The on-chip OSD controller is available for creating bitmapped OSD menus
•The keypad buttons utilize the input of the on-chip low bandwidth ADC.
•Software IR decoders is used with an external remote controller.
•One of the on-chip PWM outputs is used for controlling back-light intensity
•Integrated LVDS transmitters to LCD panels with integrated LVDS receivers.
The LCD panel resolution supported can be up to SXGA resolutions.
6. LCD PANEL INTERFACE
The L5-A board can drive panels both with LVDS and TTL interfaces. The footprints for
single LVDS and double LVDS connectors are available on the board (S503 and S502,
respectively). Either of these connectors can be used without any changes on the board.
The TTL interface is supported by a daughter board (S506 is the connector for the
daughter board). For the TTL case, connecting the daughter board to the connector will be
sufficient.
A Hirose 30-pin connector (S502) is used for double LVDS link from the board to various
LVDS panels. This connector can also be used for single LVDS, but another connector
footprint (S503) is available for single LVDS purposes. Using only S503 for single LVDS
panels decreases the cost. The LVDS traces are routed differentially from the gm2221 IC
to the connector. These are 100-Ohm differential traces.
