5-3 SIMPLE-INTRODUCTION about LM700 chipset
1. GMZAN1 ( all-in-one chip solution for ADC, OSD, scalar and interpolation) :
USE for computer graphics images to convert analog RGB data to digital data with interpolation process,
zooming, generated the OSD font , perform overlay function and generate drive-timing for LCD-PANEL.
2. M6759 (ALI- MCU, type 8052 series with 64k Rom-size and 512 byte ram) :
Use for calculate frequency, pixel-dot , detect change mode, rs232-communication, power-consumption
control, OSD-index warning , …etc.
3. 24LC21 (MicroChip IC) :
EePROM type, 1K ROM-SIZE, for saving DDC-CONTENT.
4. 24C04 (ATMEL IC) :
EePROM type, 4K ROM-SIZE, for saving AUTO-config data, White-balance data, and Power-key status
and Backlight-counter data.
5. LM2569S( NS brand switching regulator 12V to 5V with 3A load current) .
6. AIC 1084-33CM (AIC brand linear regulator 5V to 3.3V)
7. LVDS ( use NOVATEK NT7181F)
Convert the TTL signal to LVDS signal
The advantage of LVDS signal is : the wire can be lengthen and eliminate wire number , low EMI .
LVDS signal is high frequency but low voltage, only 0.35 VPP ,the frequency is seven times higher than TTL
MODULE-TPYE COMPONENT :
1. ADAPTER : CONVERSION-module to convert AC 110V-240V to 12VDC, with 5.0 AMP
2. INVERTER : CONVERSION-module to convert DC 12V to High-Voltage around 1600V, with frequency
30K-80Khz, 7mA-9Ma
