Overview: STLC7550 LOW POWER LOW VOLTAGE ANALOG FRONT END . . . . . . . . . . . . . . . . GENERAL PURPOSE SIGNAL PROCESSING ANALOG FRONT END (AFE) TARGETED FOR V.34bis MODEM AND 56Kbps MODEM APPLICATIONS 16-BIT OVERSAMPLING Σ∆ A/D AND D/A CONVERTERS 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 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 3µW at 3V PROGRAMMING SAMPLING FREQUENCY MAX. SAMPLING FREQUENCY : 45kHz SYNCHRONOUS SERIAL INTERFACE FOR PROCESSOR DATAS EXCHANGE. MASTER OR SLAVE OPERATIONS 0.50µm CMOS PROCESS TQFP44 PACKAGE STLC7546 MODE OF OPERATION COMPATIBLE 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. TQFP44 (10 x 10 x 1.

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 application processor : Pentium, Risc or DSP processors.
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).
