5. SYSTEM DIAGRAM AND APPLICATIONS
controllers in the chip and interfaces to PCI bus directly. In addition, W6692 provides peripheral control circuits for PCM
CODEC and POTS interface.
The all-in-one characteristic of W6692 makes it excellent for passive ISDN PCI card. W6692 integrates three HDLC
In the following application, only a few TTL-like glue circuits are needed for the two POTS interface control.
W6692 also integrates the 8-bit Intel or Motorola microprocessor interface which makes it excellent for TA application.
Typical applications include :
- PCI passive S-card for data only service
- PCI passive S-card with one handset/POTS connection
- PCI passive S-card with two POTS connections
- ISDN TA or other embedded application
