Description
The W66920F is a single chip PCI bus ISDN S/T interface controller suitable for ISDN internet access. It integrates three HDLC controllers, one for the D channel and two for the B channels, which allows efficient access to signaling and data services. The chip also features a PCM codec interface for voice service or other services. With a built-in PCI 2.2 interface circuit, it enables glueless design for PCI bus add-on card applications.
Specifications and Features
