GENERAL PURPOSE SIGNAL PROCESSING  
ANALOG FRONT END (AFE)  
TARGETED FOR V.34bis MODEM AND  
56Kbps MODEM APPLICATIONS  
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 de-  
sign in saving external logical glue.

DESCRIPTION  
The STLC7550 is a single chip Analog Front-end  
(AFE) designed to implement modems up to  
56Kbps.  
It has been especially designed for host processing  
application in which the modulation software  
(V.34bis, 56Kbps) is performed by the main applica-  
tion processor : Pentium, Risc or DSP processors.  
TQFP48 (7 x 7 x 1.40mm)  
The main target of this device is stand alone appli-  
ances as Hand Held PC (HPC), Personnal Digital  
Assistants (PDA), Webphones, Network Comput-  
ers, Set Top Boxes for Digital Television (Satellite  
and Cable).  
(Full Plastic Quad Flat Pack)  
ORDER CODE : STLC7550TQF7  
To comply with such applications STLC7550 is  
powered nominally at 3V only.
