FUNCTIONAL DESCRIPTION
MediaQ Incorporated
CPU Interface
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:
