OSD - and + buttons

Standby button

❒ ON/OFF Switch

The projector shall have a AC mains power control switch visible and accessible on the

end of the projector, near the video and AC inlets.

❒ Indicator LED

There shall be an LED located in the Standby button which lights green when the projector

is powered on with a stable and usable display. The color shall change from green to

yellow to indicate it is in the suspend or standby modes.

❒ Projector Input Signal Selection

There is no input signal select switch on the projector itself. It is achieved either via the

projector OSD, pushing the Source button on the multimedia adapter or by pressing the

Source button on the remote control.

❒ On-Screen Display Pushbuttons

There shall be three side panel buttons, a Select button, a Plus(+) button, and a Minus(-)

button, for controlling the On Screen Display (OSD) which provides a means of adjusting

projector parameters.

❒ Standby Function

This button is used to instantly put the projector into a “standing by” sequence. When

pressed, first the projector switches from the displayed video to the “Going to Standby”

information screen. Then, after approximately a 10-second delay, the lamp shuts off and

the color wheel stops. The fans continue to operate to cool the lamp and projector, and then

they also shut off when the internal temperature reaches a comfortable temperature. The

electronics remains powered to expeditea restart. The Standby button LED flashes for

approximately 45 seconds to indicate the projector cannot be restarted during this time.

When the Standby LED stops flashing, the button can then be pressed so the lamp, color

wheel and fans all restart to restore full functionality.

❒ Resync Button

This button is to the right of the OSD control buttons. When it is pressed, the micro-

controller shall enter a routine to remeasure the sync frequencies, optimize the clock, clock

phase and reset the size and centering of the image on the screen. The settings realized by

this function shall override any previous user settings for this mode. These shall then be

overridden by any user adjustments subsequently made through the OSD, until the next time

this button may be pressed for this mode.

❐ Analog Input The AD9884 is a complete 8-bit Msps monolithic analog interface

optimized for capturing RGB graphics signals from personal

computers and workstations. Its 140 Msps encode rate capability

and full-power analog bandwidth of 500 MHz supports display

resolutions of up to 1280*1024 (SXGA) at 75Hz with sufficient

input bandwidth to accurately acquire and digitize each pixel.

To minimize system cost and power dissipation the AD9884

includes an internal +1.25V reference, PLL to generate a pixel

clock from HSYNC, and programmable gain, offset, and clamp

circuits.

❐ Digital Input The SiI 141 uses PanelLink Digital technology to support displays

ranging from VGA to High Refresh XGA (25-86 MHz), with a

flexible single or dual pixel out interface and selectable output

drive, the SiI 141 receiver supports up to true color panels (24

bit/pixel, 16.7M colors) in 1 pixel/clock mode (18 bit/pixel in a

pixel/clock mode). PanelLink also features an inter-pair skew

tolerance up to 1 full input clock cycle and a highly jitter tolerant

PLL design.

PanelLink Digital technology simplifies PC design by resolving

many of the system level issues associated with high-speed digital

design, providing the system designer with a digital interface

solution that is quicker to market and lower in cost.

❐ DMD The DMD 8460_A is a spatial light modulator that consists of an

848(H)*600(V) array of aluminum micro-mechanical mirrors on a

17-micrometer(um) pitch. Each mirror can be individually

deflected at an angle of +/- 10 degrees about a hinged diagonal

axis. The deflection angle (positive or negative) of the mirrors

can be individually controlled by means of underlying CMOS and

addressing circuitry and mirror reset signals. Effectively, the DMD

is an electrical input, optical output memory device.

SERVICE MANUAL

Martin 2-9

❐ Image Processor The PW264 is a highly integrated “system on a chip” that

interfaces computer graphics and video inputs in virtually any

format to a fixed frequency flat panel display.

An embedded DRAM frame buffer and memory controller

perform frame rate conversion.

Horizontal and vertical image scalars coupled with intelligent

frame locking circuitry create sharp images, centered on the

screen, without user intervention.

Computer images from VGA to SXGA resolution input to the chip

can be resized to fit on the target display device, which can also

have any resolution up to XGA.

Video data from 4:3 aspect ratio NTSC or PAL and 16:9 aspect

ratio HDTV or SDTV is supported. Nonlinear scaling and

separate horizontal and vertical scalars allow these inputs to be

resized optimally for the native resolution of the display device.

An on-chip microprocessor and an included embedded software

suite allow manufacturers to develop feature rich products.

Programmable features include the user interface, custom start-up

screen, all automatic imaging features and special screen effects.

An evaluation kit is a available to streamline the design process

and reduce product development time.

The PW264 requires a minimum of external components. With the

incorporation of the frame buffer, resizing circuitry, and micro

processor and peripherals into the chip, the number of

interconnects and the circuit board size is reduced, leading to

lower costs.

❐ Memory The TE28F400B3T is a nonvolatile, electrically block-erasable

(Flash), programmable read-only memory containing 4,193,304

bits organized as 262,144 words by 16 bits or 524,288 words by

18 bits. Smart Voltage Technology (SVT) provides industry-

standard, multi- or single-voltage, dual-supply operation. Writing

or erasing the device is done with either a 5V or 12V VPP

voltage,while all operations are performed with a 3.3V or 5V

VCC. It is fabricated with Micron’s advanced CMOS floating-

gate process.

The MT28F400B1 is organized into seven separately erasable

blocks. To ensure that critical firmware is protected from

accidental erasure or overwrite, the MT28F400B1 features a

hardware-protected boot block.

❐ SDRAM The SDRAM provides for grammable READ or WRITE burst

lengths of 1, 2, 4 or 8 locations, or the full page, with a burst

terminate option. An AUTO PRECHARGE function may be

enabled to provide a self-timed row precharge that is initiated at

the end of the burst sequence.

The 1 Meg X 16 SDRAM uses an internal pipelined architecture

to achieve high-speed operation. It is designed to operate in 3.3V

low-power memory systems. All inputs and outputs are LVTTL-

compatible.

❐ Micro Controller The H8/300 CPU is a high-speed processor with an architecture

featuring powerful bit-manipulation instructions, ideally suited for

realtime control applications. The on-chip supporting modules

implement peripheral functions needed in system configurations.

These include ROM, RAM, four types of timers (a 16-bit free-

running timer, 8-bit timers, PWM timers, and a watchdog timer), a

serial communication interface (SCI) and I

C bus interface

(option), a host interface (HIF), an A/D converter, a D/A

converter, and I/O ports.

❐ Data Formatter DPF2A is an Application Specific Integrated Circuit (ASIC)

intended for use in DMD Display system applications. It provides

digital RGB/YUV signal conditioning, DMD image processing

and DMD data formatting. It is designed to work in conjunction

with two banks of external SDRAM and external Data Format

Controller. DPF2A’s operation is programmable via a serial P-

Bus Interface and relies on external inputs for real time control.

❐ ASIC The Display Controller is an Application Specific Integrated

Circuit (ASIC) intended for use in DMD (Digital micro-mirror

device) systems. The ASIC performs a variety of functions, some

of which are controlling the data flow between DPF2A, memory,

and the DMD as well as generating the DMD reset waveform. The

Display Controller is designed to work in conjunction with two

banks of external SDRAM (type 1M*16), an external SR16C and

an external DPF2A ASIC.

❐ Color Wheel Controller The A8902CLBA is a three-phase brushless dc motor controller/

driver for use in 5V or 12V hard-disk drives. The three half-

bridge outputs are low on-resistance n-channel DMOS devices

capable of driving up to 1.25A. The A8902CLBA provides

complete, reliable, self-contained back-EMF sensing motor

startup and running algorithms. A programmable digital frequency-

locked loop speed control circuit together with the linear current

control circuitry provides precise motor speed regulation.
