SiS 307ELV which is an accompany chip of SiS VGA chip, integrates
a. An LVDS transmitter with bi-linear scaling capability for TFT LCD panel display
All the above functions can support dual-display features. It means that the second display device driven by SiS307ELV can display independent resolutions, color depths and frame rates different from the primary VGA chip. SiS307ELV receives digital video signals and control signals from the primary VGA chip then transforms them into LVDS signals for LCD display.
The output display combination can be one of the two three:
(1) primary CRT+SiS307ELV TV,
(2) primary CRT+SiS307ELV LCD.
The package type of SiS307ELV is 169-pin BGA.
