STLC7550

Low Power Low Voltage Analog Front End

Features

■ General purpose signal processing Analog

Front End (AFE)

■ Targeted for V.34bis Modem and 56Kbps

Modem applications

TQFP48 (7 x 7 x 1.4mm)

(Full Plastic Quad Flat Pack)

■ 16-BIT oversampling Σ∆ A/D and D/A

converters

It has been especially designed for host

processing application in which the modulation

software (V.34bis, 56Kbps) is performed by the

main application processor : Pentium, Risc or

DSP processors.

■ 83dB signal to noise ratio for sampling

frequency up to 9.6kHz @ 3V

■ 87dB dynamic range @ 3V

■ Filter bandwidths:

0.425 x the sampling frequency

The main target of this device is stand alone

appliances as Hand Held PC (HPC), Personnal

Digital Assistants (PDA), Webphones, Network

Computers, Set Top Boxes for Digital Television

(Satellite and Cable).

■ On-chip reference voltage

■ Single power supply range: 2.7 to 5.5V

■ Low power consumption less than 30mW

operating power 3V

■ Stand-by mode power consumption less than

3mW at 3V

■ Programming sampling frequency

■ Max. sampling frequency : 45kHz

■ Synchronous serial interface for processor

datas exchange Master or Slave operations

■ 0.50µm CMOS process

■ TQFP48 package

■ STLC7546 mode of operation compatible

To comply with such applications STLC7550 is

powered nominally at 3V only.

Maximum Power Dissipation 30mW is well suited

for Battery operations. In case of battery low,

STLC7550 will continue to work even at a 2.7V

level.

STLC7550 also provides clock generator for all

sampling frequencies requested for V.34bis and

56Kbps applications.

This new AFE can also be used for PC mother

boards or add-on cards or stand alone MODEMs.

It can be used in a master mode or slave mode.

The slave mode eases multi AFE architecture

design in saving external logical glue.

Description

The STLC7550 is a single chip Analog Front-end

(AFE) designed to implement modems up to

56Kbps.
