W6692 Datasheet, PDF (9/104 Pages) Winbond – PCI Bus ISDN S/T-Controller

Preliminary Data Sheet
1. GENERAL DESCRIPTION
W6692 PCI ISDN S/T-Controller
The Winbond's single chip PCI bus ISDN S/T interface controller (W6692) is an all-in-one device suitable for ISDN Internet
access. Three HDLC controllers are incorporated in the chip, one for D channel and the other two for B channels. These HDLC
controllers facilitate efficient access to signaling and data services. The PCM codec interface provides voice service or other
services. The built in PCI 2.2 interface circuit makes glueless design for PCI bus add-on card application.
