DESCRIPTION

The DSP sofware is extensively user configurable

allowing specific functions to be supported like

Caller Identifier (CLID) and Second Call Waiting

Identifier (SCWID).

The DSP software includes a transparent mode

allowing the host controller to access directly the

modem Analog Front End and the Audio AFE

through the dual Port RAM. This is very useful for

hostprocessing modem solutions (or soft modem)

where the modulation andthe demodulation(V.34,

V.90) are done by the application main processor.

In transparent mode, the embedded DSP can be

used simultaneously with the same samples.

ST75C530 and ST75C540 are two super-inte-

grated devices including DSP, Modem and Audio

Analog Front Ends and memories for Telephony,

Modem and FAX applications.

These devices can be used for classical applica-

tions over POTS lines or over Internet.

The super integration technology allows a signifi-

cant cost reduction on bill of materials for equip-

ment like High-End phones, INTERNET phones,

phone-Fax, INTERNET FAX, ...

The devices are used with a host processor

through a Dual Port RAM allowing the use of any

kind of microcontroller (RISC, CISC, General Pur-

The transparentmode for audio AFE is providedto

play audio files or to record voice and/or audio.

pose 8-bit C, ...).
