SiS 307CP 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. A single link TMDS transmitter with excellent 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 SiS307CP can display independent resolutions, color depths and frame rates different from the primary VGA chip. SiS307CP 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, TMDS signals for LCD display.

The output display combination can be one of the four:

(1) primary CRT+SiS307CP TV,
(2) primary CRT+SiS307CP LCD,
(3) SiS307CP TV+SiS307CP LCD.

The package type of SiS307CP is 16928-pin BGA.
