4. Circuit Description

1. Power supply (DC/DC Converter):

1.1 IC251 BA9741F is a two-channel switching regulator controller that uses PWM method. For DC to DC conversion for step-down. It converts a 12V DC into regulated and stable output voltage of 5V.

1.2 Regulator: IC252, IC253, IC254, IC255 function is to convert 5V into regulated and stable O/P of 3.3V and 2.5V. IC252 converts 5V to 2.5V; converts 5V to 3.3V; IC253, IC254, IC255.

2. DDC data select:

2.1 IC601 is save D-SUB DDC data.

2.2 IC606 save DVI-A analog DDC data, IC605 save DVI-D digit DDC data. IC604 is triple 2 channel analog multiplexes / de-multiplexes, IC604 pin 10 & 11 is “Lo” select IC605 DDC data, IC604 pin 10 & 11 is “Hi” select IC606 DDC data.

3. ADC (Analog): The IC608 AD9888 is a complete 8-bit, 205MSPS monolithic analog interface optimized for capturing RGB graphics signal

from PC. The IC608 have two input source (D-SUB & DVI-A), the input source control by I

4. TMDS (DVI): The IC609 THC63DV161 is a TMDS receiver compliant with DVI Rev. 1.0. The IC609 turn on/off control by pin 2 “DPD” from IC401 scaler.

5. Scaler: The PW166B image processor is a highly integrated “system-on-a-chip” that interfaces analog, digital, and video inputs in virtually any format to a digital projection system or multimedia display.

Any embedded SDRAM frame buffer and memory controller perform frame rate conversion. Computer images from VGA to UXGA at almost any refresh rate can be resized to fit on a fixed-frequency target display device with any resolution up to UXGA with full 24-bit color.

The PW166B includes advanced second generation image scaling that provides completely programmable, horizontal and vertical image scaling.

The PW166B also includes advanced second-generation sync decoding which provides full support for a wide variety of sync types. This includes interlaced, progressive, sync-on-green, and TMDS DE (Data Enable) only.

An integrated OSD controller provides bit-mapped based OSD with 16 colors from a 64K color palette. The OSD controller supports transparent and translucent functions.

The Graphics Port (GPort) captures computer graphics inputs with very high input bandwidth through an external IC608 Analog-To-Digital converter (ADC) or IC609 digital interface receiver.

The DPort is designed to be connected directly to LVDS (IC501, IC502). The output timing is fully programmable and is independent of the input timing. An on-chip 80x86 microprocessor with custom features for image processing applications is provided. Built in port interrupts,

General Purpose I/O (GPIO), UART, IR Decoders, Timers and PWM Generator provide a full featured hardware base to build on.

6. LVDS Transmitter: The IC501, IC502 transmitter converts 28 bits of CMOS/TTL data into LVDS (Low Voltage Differential Signaling) data stream.

A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link.

7. USB HUB Controller: IC951 is a high speed USB HUB controller, this single-chip device incorporates one upstream and four downstream USB

transceivers. IC951 CY7C65640 includes interface signals for external port power switches. The power switching and over-current detection

of downstream ports is managed by control pins connected to an external power switch device by IC952 & IC953. IC954 is an EEPROM VID & PID configured.

5. Adjusting Procedure

A. General.

1. All specification must be met over line voltage range of 90V

2. Operating temperature range is 0

C to 40oC with a relative humidity of 10% or less to 80%.

3. The monitor must be operational in a usable state within 30 minutes after turn-on.

4. All signal levels are measured assuming termination at the monitor’s input jacks or in its characteristic impedance.

5. All controls must have excess range (no control may be left at an end stop when proper alignment is completed).

6. The monitor is not required to meet specs during the following but must tolerate, without damage to the LCD or circuits,

any sequence or combination of power on and off, signal on and off, erratic, wrong frequency or noisy inputs while at any

possible unplugging of power or signal, settings of user accessible controls likewise, the monitor should survive extended periods of operation with line voltage reduced below the specified minimum.

7. An isolation transformer should be used when performing alignment and tests, Portions of the power supply board are hot

ground, The remaining boards are cold ground.

8. Ambient condition:

8.1 Illumination: 150 ~ 260 lux.

8.2 Environmental noise: Less than 60dB.

8.3 Interference of EMI: No excessive electric or magnetic fileds.

8.4 Temperature: 24 ± 2

8.5 Humidity: 65 ± 20%.
