Datasheet
4.8.12.
Flat Panel/Digital CRT Interface / 1.8V TV-Out Interface
The GMCH has a dedicated port for Flat Panel support. This port is a 16 bit digital port (4 control bits
and 12 data bits) with a 1.8V interface for high speed signaling. The port is designed to connect to
transmission devices. The port can also be used to interface with an external TV encoder that requires
1.8V signals.
Connecting the GMCH to a flat panel transmitter is demonstrated below. For more details, refer to The
Intel
815 Chipset Design Guide
or the
Intel
815E Chipset Design Guide
.
The GMCH supports a variety of Flat Panel display modes and refresh rates that require up to a 65 MHz
dot clock over this interface. Table 20 shows some of the display modes supported by the GMCH.
The GMCH supports scaling for all of the resolutions listed in Table 20. Actual scaling results are
dependant on the third party flat panel transmitter. If the flat panel transmitter does not support scaling,
the resolutions are supported by the GMCH via centering.
Table 21 shows some of the TV-Out modes supported by the GMCH.
