1.5 General
• Subsystem (board) vendor ID support for board
identification via software driver
• Internal arbitration control
• Diagnostic support and event analysis
• Programmable Vertical Blanking Interval (VBI) data
region for e.g. to support INTERCAST, teletext, closed
caption and similar applications
• 3.3 V supply enables reduced power consumption, 5 V
tolerant I/Os for 5 V PCI signalling environment.
2 GENERAL DESCRIPTION
The SAA7146A, Multimedia PCI-bridge, is a highly
integrated circuit for DeskTop Video (DTV) applications.
The device provides a number of interface ports that
enable a wide variety of video and audio ICs to be
connected to the PCI-bus thus supporting a number of
video applications in a PC. One example of the application
capabilities is shown in Fig.49.
Figure 1 shows the various interface ports and the main
internal function blocks.
