Preliminary Data Sheet
5. SYSTEM DIAGRAM AND APPLICATIONS
W6692 PCI ISDN S/T-Controller
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
The all-in-one characteristic of W6692 makes it excellent for passive ISDN PCI card. W6692 integrates three HDLC
controllers in the chip and interfaces to PCI bus directly. In addition, W6692 provides peripheral control circuits for PCM
CODEC and POTS interface.
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.
