SiS 307LV which is an accompany chip of SiS VGA chip, integrates a. A NTSC/PAL video encoder with Macrovision Ver.7.1.L1 option for TV display.
b. HDTV video encoder which supports 480i, 480p, 720p and 1080i output modes
c. 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 SiS307LV can display independent resolutions, color depths and frame rates different from the primary VGA chip. SiS307LV receives digital video signals and control signals from the primary VGA chip then transforms them into composite, S or component video output for TV display, LVDS signals for LCD display.
The output display combination can be one of the three:
(1) primary CRT+SiS307LV TV,
(2) primary CRT+SiS307LV LCD,
(3) SiS307LV TV+SiS307LV LCD.
The package type of SiS307LV is 169-pin BGA.
