SAA5284
13 APPLICATION INFORMATION
13.1
Hardware application circuit for ISA card
A typical application circuit diagram (for the ISA card
application) is shown in Fig.10.
13.2
Hardware application circuit for PCI application
This PCI application is based around the Philips SAA7146
video to PCI bridge IC. SAA7146 has a ‘Data Expansion
Bus Interface’ (DEBI) which is an Intel/Motorola style
16-bit parallel interface. This is used to facilitate
communications to SAA5284.
The application circuit diagram is shown in Fig.11.
13.3
Software application information
PC application software is available providing two levels of
interface. At a low level a VxD based driver offers generic
packet gathering and buffering. Full support is provided for
ISA based applications with facility for PCI based
applications. Higher level support is provided by a series
of DLLs. These perform normal teletext display generation
and page management.
