4. THEORY OF OPERATION

This section describes the function of the LCD monitor per functional block.L7EA monitor includes MB board, audio board (option), inverter board, adapter and button board.

4.1 MB BOARDThe MB board is a four-layer, single-landed design with ground and internal planes provided. DC power from the power adapter enter the board through DC jack. Other connectors on the board are for inverter,audio and button board .The VGA cable is a signal cable that contains video signal, sync signal and DDC signal from PC VGA adapter.This system board consists of 4 functional areas : flat panel controller, flash ROM , power regulator andLVDS transmitter.

4.1.1 Flat panel controller…… gm2120 (U8)The heart of the system board is Genesis gm2120. The gm2120 is a graphics processing IC for LCD monitor. It provides all key IC functions required for LCD panel. On-chip functions include a

high-speed triple-ADC , PLL, high sacling engine, OSD controller and on-chip microcontroller.

a) Clock Generation : Crystal Input Clock (TCLK and XTAL). This is the input pair to an internal crystal oscillator and corresponding logic. A 14.318 MHz crystal is recommended.

b) Hardware Reset ( Pin 5 )Hardware Reset signal is generated by MAX6326 (U10).It assert a reset signal at least 100 ms.c) Analog to Digital ConverterThe gm2120 chip has three ADC's (analog-to-digital converters), one for each color (red, green and blue)The analog RGB signals are connected to gm2120 as described below

d) OSD :The gm2120 has a fully programmable ,high-quality OSD controller.The on-chip static RAM(4096 wordsby 24 bits) stores the cell map and the cell definitions.

e) On-Chip Microcontroller (OCM)The gm2120 on-chip microcontroller(OCM) serves as the system microcontroller.That is , it programs the gm2120 and manages other devices in the system such as the keypad, the backlight, LED, audio and non-volatile RAM.using general purpose input/output (GPIO) pins.

L7EA (AL708) 4-1

f) Panel Power Sequencing ( PPWR, PBIAS) ( Pin 113~114)20 has two dedicated outputs PPWR and PBIAS ( Pin113 and Pin114) to control LCD power sequencing once data and control signals are stable.

g) Parallel ROM Interface Port (Pin 8~25, Pin28~35)The gm2120 has parallel ROM interface port , pin8~25 for address bus, pin28~35 for data bus.

h) Panel interface (Pin 55~66, Pin69~80, Pin83~87, Pin90~96.Pin99~110)The gm2120 driver interface is highly programmable. It supports dual bus / dual port for SXGA drivers.

4.1.2 LVDS Transmitter DS90C383 (U1,U2)The DS90C383 transmitter converts 28 bits of TTL data into four LVDS ( Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams

over a fifth LVDS link. At a transmit clock frequency of 85 MHz, 24 bits of RGB data and 3 bits of LCD

timing and control data ( FPLINE, FPFRAME, DRDY) are transmitted at rate of 595 Mbps per LVDS

data channel. U1 AS the ODD pixel transmitter , U2 as the EVEN pixel transmitter.

4.1.3 Power Regulator AIC1563 (U12),LT1117 (U5, U6)The AIC1563 is a monolithic control IC containing the primary functions required for DC to DC converters.The device consists of an internal temperature compensated reference, conparator, controlled duty cycle oscillator with an active current sense circuit. Desired output voltage are determined by the equation

Vout = 1.25 ( 1 + R104 / R103), In this case, the output voltage are 5 Volts.The AIC1117 is a low dropout positive adjustable regulator with minumum of 1A output current capability.So it is well suited for 3.3 V and 2.5 V Rregulator. U6 as a 2.5 V regulator , Desired output voltage are determined by the equation

Vout=5 x ( R53 / R53+R56)= 2.5

U5 as a 3.3 V regulator , Desired output voltage are determined by the equation

Vout=5 x ( R30 / R30+R36)= 3.3

4.2 Audio Board AN7522 (U1)The AN7522 is a 2 channel audio power amplifier capable of delivering 2W of continuous average power to an 8 ohms with less than 0.5% (THD) from a 12 V power supply.

An7522 can directly drive 8 ohms speaker , does not require output coupling capacitor, bootstrap capacitor ,or snubber network. Audio line-in are feed into pin 6,8 of the AN7522. The output power is controlled bythe DC voltage of pin 8 from gm2120 GPIO port.
