Power measurement jumpers for FVDD (flat panel),
BVDD (Bus), USBVDD (USB), AVDDOSC (Oscillator
I/O ESD), CVDD13 (SRAM) and CVDD24 (Core).
Normal operation requires either these jumpers or resistors
R57, R58, R59, R60, R61 and R62 installed. Both jumper
and associated resistor removed when measuring power.
PLATFORM SETUP INSTRUCTIONS
The MQ-1132 / PCI Evaluation Board is used in conjunction with a motherboard with a PCI interface.
The followings components are required :
§
A complete PC motherboard system containing a PCI interface slot
§
A flat panel (i.e. Sharp HR TFT- LQ039Q2DS54)
§
Windows 2000/NT
FUNCTIONAL DESCRIPTION
Flat Panel Interface
The MQ-1132 / PCI Evaluation board has two connectors intended for interfacing to a variety of flat
panel displays. Connector U12 is used to interface directly to a Sharp HR TFT display (LQ039Q2DS54).
The MQ-1132 evaluation board has all the necessary power and power sequencing circuitry necessary for
this panel. Following are directions to connect the flat panel cable to the evaluation board:
§
Lift the brown lever on the HR TFT socket (U12)
§
Insert the flat cable with the 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
Also provided, is a Generic Flat Panel connector (JP1) that can be used to interface the evaluation board
to panels other than the Sharp HR TFT. Cus tom cables are required to map the panel signals onto the
proper MQ-1132 pins. The cable requires a matching female connector to mate with the 60-pin, 50-mil,
2x30 male connector on the evaluation board. The part number for the female connector is M50-
