Introduction

1.1

Feature List

Functions

– G.723 V5.1 Compression/Decompression (6.3,

5.3 Kbit/s)

– Accepts/outputs uncompressed audio in 8-bit PCM

A/µ law or 16-bit linear format

P-TQFP-100

– G.711 Compression/Decompression (64 Kbit/s)

– Uncompressed/compressed audio switchable between different interface

combinations (IOM® /Serial Audio Interface, IOM/Host, Host/Host)

– Inband controlled H.221/H.223 oriented audio protocol, e.g. for direct serial

connection to Videocodec (VCP of 8 × 8 Inc., formerly IIT Inc.) as well as host based

solutions

– Outband controlled audio protocol with optimized data rate

– Stable reaction on interrupt handshake timing violations of e.g. a slow host

(Windows® PC)
