This guide is intended to give a brief overview of the MQ-1168 and describe the features and workings of
the MQ-1168 / PCI Evaluation Board. This includes how to locate connectors, configure switches,
configure jumpers, and the initialization and configuration of this Evaluation board with the PC
motherboard with PCI interface as well as other platforms by using special adapters.
MQ-1168 OVERVIEW
The MQ-1168 is the second generation product in the MQ-11xx series from MediaQ. This device
provides rich video and audio functions in addition to high performance graphics and high speed
peripherals designed to give the user a complete multimedia experience. The MQ-1168 integrates a 64-bit
2D graphics engine, a flexible LCD display interface, dedicated Video Input port (VI), Secure Digital
interface (SD), Serial Peripheral Interface (SPI), AC-97/I2S audio and USB controllers (function and host)
on a single chip. The MQ-1168 has a 64-bit wide internal bus to 320KBs of embedded memory providing
scalable bandwidth of up to 384MB/sec for the frame, video, USB and audio buffers. The MQ-1168
directly supports connection to the Intel SA-1110 and PXA2x0, the Motorola Dragonball series, the NEC
VR-4100 family and the Hitachi SH-3/SH-4 CPUs as well as 32bit PCI.
PLATFORM DESCRIPTION
When installed into a PCI slot of a standard PC motherboard, the Evaluation Board can provide a
development and verification platform for hardware and software. Using an adapter card, specified at the
time of order placement, the Evaluation board can also be used in conjunction with other development
environments. Adapters are currently available for the Intel PXA2X0 Lubbock, SA-1110/1111
Assabet/Neponset, Palm Hurricane, Hitachi S1 (or equivalent) and NEC VR4121 Falcon development
platforms.
The location of the connectors, jumpers and other notable features are shown on the layout diagram

The Evaluation card can be used as is in a PCI system. For other supported platforms an adapter is
installed on the back of the board mating with J2. Details of which adapters are available and how to use
them are contained in the section “Adapters” later in this document. The CPUs supported by this means
are the Intel SA-1110 and PXA2x0, Motorola Dragonball, NEC VR4121 and Hitachi SH7709/7750. Care
should be taken to ensure that pins A1/B1/C1 match on the main board and adapter. When used in a PCI
system, the adapters must be removed or damage can occur to the Evaluation board and/or system. The
user must support the panel, Evaluation Board (non-PCI environment) and adapter to avoid undue strain
on the various connectors.
Flat Panel Interface
The Evaluation board has three connectors intended for interfacing to a variety of flat panel displays.
Connector U1 is used to interface directly to a Sharp HR TFT display (LQ039Q2DS54 or equivalent).
The Evaluation board has all the necessary power and power sequencing circuitry necessary for this panel.
The Sharp HR TFT flat panel cable can be connected to the Evaluation board as follows:
§ Lift the brown lever on the HR TFT socket (U1)
§ Insert flat cable with exposed portion facing up over the lever and under the top of the socket
§ Push down the brown lever – this should lock the cable into place and make electrical connection
Two Generic Flat Panel connectors (J3 and J5) are provided to allow the Evaluation board to be interfaced
with a wide variety of LCD panels other than the Sharp HR TFT. Custom cables are required to map the
panel signals onto the proper MQ-1168 pins, details of the LCD panels already verified by MediaQ can be
obtained from our web site. A custom cable will require a matching female connector to mate with either
of the 60-pin connectors J3 or J5, these connectors also supply various power rails. The connector J3 is a
50-mil, 2x30 male connector and J5 is a 0.1” 2x30 standard header. The matching female 50 mil spaced
connector part number is M50-3003022. The mating connector for the 0.1” header is readily available in
many variations.
The pin assignments for the generic connectors are the same and shown below:
Board Revision 2
Care must be taken when fabricating cables to ensure that pins do not short together as this could cause
damage to either the MQ1168 or the panel and even in some instances to both.
Touch Screen / MMC
The Evaluation board supports a touch screen controller connected to the SPI interface of the MQ-1168
controller. Connector J2 mates with the flat cable connected to the touch panel provided with the Sharp
HR TFT display (LQ039Q2DS54). To install the cable, pull out the sliding black portion of the socket,
insert the cable bare metal side up and then push the black portion back in locking the cable in place.
USB
Two USB connectors are provided on the Evaluation board. CN2 is a Type A USB connector and
provides the USB Host functionality of the MQ-1168. CN1 is a Type B connector and provides the USB
Device function. Since the MQ-1168 USB device is a high speed device, CN1 is configured as such.
Video
The board includes a Conexant Video Decoder (Bt835) which outputs VIP data compatible with the MQ-
1168. Both composite and S-Video input sources are supported on J1 and JS1 respectively. In addition,
J7 makes all the MQ-1168 video related signals available on a 30-pin standard 0.1” header. This can be
used to observe the signal activity with test equipment or to allow external VIP compliant digital video
data to be sent to the MQ-1168 instead of using the onboard decoder.
Secure Digital
The MQ-1168 Secure Digital interface is used to support either SD or MMC cards installed in the SD
socket (U3). Card detect and write protect functions are implemented.
Audio
The Evaluation board supports audio input and playback/output using either of the onboard audio
CODECs. Both a Philips I2S and Crystal AC97 audio CODEC are implemented on board. Stuffing
resistors are used to select between the two.
Audio input can come from any amplified or non-amplified audio source and uses the Phone Jack CN3.
Amplified audio output to headphones, amplified speakers or other destinations is available on the Phone
Jack CN5. A mono or stereo microphone can be connected to the Phone Jack CN4.
Power
Power is provided by the PCI interface or CPU adapter card when used. The 1.8V and 3.3V power
supplies required by the MQ-1168 are provided by regulators on the Evaluation board which are powered
off the PCI bus or adapter card. The rest of the board is powered directly by the PCI bus or adapter card.
The Evaluation board can be used with other platforms besides PCI. To accomplish this, adapters are
used that interface to a special connector on the Evaluation board and mate with the unique connectors
used on the various target platforms. At this time adapters are available to support the following
platforms:
• Intel SA-1110/1111 Development Platform (Assabet/Neponset)
• Intel PXA2x0 Development Platform (Lubbock)
• Palm Development Platform (Hurricane)
• Motorola Dragonball Development Platform
• NEC VR4121 Development Platform (Falcon)
• Hitachi SH7709/SH7750 Development Platforms (S1 or R1)
When used in a PCI system, the adapters must be removed or damage can occur to the Evaluation board
and/or system. The follow sections describe the various adapter cards and their usage.

As shown above, the adapter for the Assabet/Lubbock platforms has three connectors. J2 mates with the
“Generic CPU” connector located on the back of the Evaluation board. Connector U1 mates with either
of the female connectors on the Assabet platform. This connector is keyed so cannot be installed
incorrectly. Connector U2 is not used with the Evaluation board.
The adapter can be configured to work on either the Assabet or Lubbock platforms. This is done by
installing three 0 ohm resistors in R3, R5 and R8 (Assabet) or R4, R6 and R7 (Lubbock). The diagram
above shows the adapter configured for the Assabet platform.
Board Revision 2
Jumpers J1 and J2 are used to select the 3.3V (J2) and 5V (J1) power sources for the Evaluation board.
Jumpering 1-2 selects power directly from the bus while 2-3 selects power from the regulators on the
adapter that receive their power from the AC adapter used by the platform.
Lubbock Platform
The Lubbock platform has a single 140-pin connector, J26 that interfaces to the adapter board (described
earlier) that re-routes several signals necessary to work with the Evaluation board. The final assembly
should resemble the diagram below which is a side view of the Lubbock platform and Evaluation Board.

MQ-1132/1168 SA-1110 &
PXA2x0 Adapter Board
PXA2X0 (Lubbock) Platform
The MQ1168 peripherals with the exception of the flatpanel interface need to signal the PXA2x0 on the
Lubbock platform with an interrupt. Our device drivers have been ported to use GPIO 10/RTC on the
Lubbock connector as the interrupt pin. GPIO 10 comes out on connector J21 pin 3 as defined in the
Lubbock user guide on page 2-13. If you intend to use GPIO 10 you need to solder a wire from the
MQ1168 interface card connector U2 pin 108 to Connector J21 pin 3. Other interrupt pins can be used by
connecting them to Pin 108 of connector U2 on the interface card, however the drivers will need to be
modified.
Assabet Platform
The diagram below shows how the Evaluation board, adapter board and Assabet platform are connected.
Care should be taken to line up the pins correctly, especially A1/B1/C1. Also, when removing the adapter
from the Assabet platform, care should be taken to ensure the boards come apart as parallel as possible or
the pins on the male adapter board connector can be bent or the plastic shroud broken.
Board Revision 2
Care should be taken to ensure correct alignment of the sockets and plugs to prevent damage during
assembly and disassembly. When removing either the Evaluation or Adapter Board from the platform,
apply even pressure is to both sides of the connector and keep the boards as parallel as possible to prevent
damage to the Plug pins and moldings.
Lubbock Platform Configuration & Operation
Consult the documentation listed below relating to the Lubbock platform for instructions on how to
configure and bring up that system.
The following instructions apply to using the Evaluation Board with the Intel StrongARM SA-1110
Reference Platform. The following components are required and should be included in the Intel
SA1110/SA1111 development package:
§ SA-1110 platform module (Assabet)
§ SA-1111 developer platform module (Neponset)
§ DC supply for platform
§ Compact flash Ethernet card, CF to PCMCIA adapter and crossover cable
§ Serial cable (10-pin female header to 9-pin female serial port connector)
Please note that no compact flash adaptor should be installed in the SA1110 board socket, as it will cause
damage to the card and the bus drivers used to drive the MQ-1168 & SA1111 board’s bus.
Software Download
After the hardware is assembled, connect the serial and ethernet connectors to a properly configured host
PC. The configuration of the host is beyond the scope of this document and should be covered in the
StrongARM documentation. Following are the steps required to download a software image to the
platform system memory.
1. Open a hyper-terminal on the host PC. The communication setting for Eboot is provided in the
Intel document “Intel StrongARM SA-1110 Microprocessor Development Board Users Guide”
2. Open the Eshell on the host PC for Window CE shell
3. Power on the system and the hyper-terminal should print some messages and stop at the point
“Init DHCP()”
4. Input an IP address here with the first three areas the same as your host PC setting (for example, if
your host PC IP address setting is 192.168.1.128, you need an IP address 192.168.1.x. The
network mask may not need to be set in which case, just press return and it will be set
255.255.255.x. Otherwise set the mask to 255.255.255.0. Hyper-terminal will print “SENT BOOTME TO 255.255.255.x.)
5. In Eshell window, select the SA-1110 device as controller device in option and set configuration
“download only on command, unselect all other option”. If setup is correct, it will print out
“Got Bootme from SA11xxxxxx, ready for download”.
6. Select the desired binary file and proceed with download. It will display download status at the
bottom left corner of the Eshell window.
7. After download, the system will reboot and execute the image file. For program information, refer
to the Intel documentation.
4. Download “Ebootdwv5.nb0” from ftp://ftp.mediaq.com/sw/mq11xx/windowsce/utils/jflash/
5. To Download image into the Neponset (SA1111) set dip switch 1, 2, 7 ON of the “SW2.”
6. To Download image into the Assabet (SA1110) set dip switch 1, 2, 7, & 8 ON of the “SW2.”
7. Once “Ebootdwv3.nb0” is flashed into the platform, select “Ethernet loader without launch” to
download image onto flash. Follow the steps required to download a software image to the
platform system memory.
8. Once image download is done, select “Program to flash” from the hyper terminal to copy image
into flash memory.
9. After program to flash is complete, perform cold boot.
The diagram above shows the adapter for the Palm Development Platform (Hurricane) or the Motorola
Development Platform. As with the other adapters, J2 mates with the “Generic CPU” connector located
on the back of the Evaluation board. Connector U4 mates with the 96-pin female DIN connector on the
Palm Hurricane Platform. Alternately, connector U6 can be used to connect to the Motorola
Development Platform. These connectors are keyed so cannot be installed incorrectly. J1 selects which
IRQ the MQ-1168 will connect to on the platform. Setting 1-2 selects IRQ2 while 2-3 selects IRQ3. The
Evaluation board requires 3.3V and 5V power from the adapter board. The Palm/Motorola adapter passes
the 3.3V power supplied on the platform connector but does not provide 5V. Connector JP1 is used to
provide 5V and can be connected to an external source. A wire with a mating female 0.25” square
connector can be attached to the 5V supply which does not go to the bus but is available on the platform.
The diagram below shows how the Evaluation board, adapter board and Palm or Mororola platforms are
connected. Care should be taken to line up the pins correctly, especially A1/B1/C1.
The diagram above shows the adapter for the NEC VR4121 Development Platform (Falcon). J6 mates
with the “Generic CPU” connector located on the back of the Evaluation board. Male 2mm pitch headers
J2, J3 and J4 mate with matching connectors on the NEC Falcon Platform. These connectors are not
keyed and care should be exercised to line up the pins correctly. When removing the adapter from the
platform, be very careful not to bend the pins. The diagram below shows how the Evaluation board, NEC
Falcon adapter and NEC Falcon platform are connected.
The adapter for the Hitachi 7709/7750 based Development Platforms (S1/R1) is shown above. J2 mates
with the “Generic CPU” connector located on the back of the Evaluation board. The Male 0.05” pitch
connector J1 mates with the matching connector on the Hitachi platforms. This connector is not keyed
and care should be exercised so as not to plug the adapter in backwards. When removing the adapter from
the platform, be very careful not to bend the pins. The adapter can be configured to work with either the
Hitachi SH7709 or SH7750 CPUs. For the SH7709 also known as the SH3 processor, R1 (10K ohm
resistor) and R4 (0 ohm resistor) should be installed. For the SH7750 also known as the SH4 processor,
R2 (10K ohm) and R5 (0 ohm) should be installed instead. These changes set the MQ1168 CPU mode
select and pull the RDY#/WAIT# line in the correct direction. Resistors R8, R9, R10 and R11 can be
removed to isolate three of the power/ground pins and the interrupt pin for use on some platforms that
were not completely pin compatible with the standard S1 connector. The diagram below shows how the
Evaluation board, Hitachi 7709/7750 adapter and Hitachi platform are assembled.
