INCA-D
PSB 21473
Overview
1
Overview
The INCA-D integrates all necessary functions for the completion of a digital voice
terminal solution.
The line transceiver of the INCA-D implements the subscriber access functions for a
digital terminal to be connected to a two wire DASL interface. It covers complete layer-1
and basic layer-2 functions for digital terminals.
Different interfaces allow the connection to a variety of devices including an Full Speed
USB interface for PC host communication.
The basic application of the INCA-D is the use in terminal equipment applications where
microphone, loudspeaker, headset or handset can be directly connected to the Analog
Frontend.
The Analog Front End and the integrated fixpoint DSP perform encoding, decoding,
filtering functions and tone generation (ringing, audible feedback tones and DTMF
signal). A full duplex echo cancellation mechanism provides high quality speakerphone
functionality.
The INCA-D is a CMOS device and operates with a single 3.3V supply.
