5. SYSTEM DIAGRAM AND APPLICATIONS
- ISDN TA, Router or other embedded application
The all-in-one characteristic of W66910 makes it excellent for ISDN embeded application. W66910 integrates three HDLC
controllers in the chip and interfaces to 8-bit microprocessor bus directly. In addition, W66910 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.
Typical applications include :
