Part Details:

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) 16-BIT oversampling A/D and D/A (Full Plastic Quad Flat Pack) converters 83dB signal to noise ratio for sampling It has been especially designed for host frequency up to 9.6kHz @ 3V processing application in which the modulation 87dB dynamic range @ 3V software (V.34bis, 56Kbps) is performed by the Filter bandwidths: main application processor : Pentium, Risc or 0.425 x the sampling frequency DSP processors. On-chip reference voltage The main target of this device is stand alone appliances as Hand Held PC (HPC), Personnal Single power supply range: 2.7 to 5.5V Digital Assistants (PDA), Webphones, Network Low power consumption less than 30mW Computers, Set Top Boxes for Digital Television operating power 3V (Satellite and Cable). Stand-by mode power consumption less than To comply with such applications STLC7550 is 3mW at 3V powered nominally at 3V only. Programming sampling frequency Maximum Power Dissipation 30mW is well suited Max. sampling frequency : 45kHz for Battery operations. In case of battery low, Synchronous serial interface for processor STLC7550 will continue to work even at a 2.7V datas exchange Master or Slave operations level. 0.50µm CMOS process STLC7550 also provides clock generator for all TQFP48 package sampling frequencies requested for V.34bis and STLC7546 mode of operation compatible 56Kbps applications. This new AFE can also be used for PC mother Description boards or add-on cards or stand alone MODEMs. The STLC7550 is a single chip Analog Front-end It can be used in a master mode or slave mode. (AFE) designed to implement modems up to The slave mode eases multi AFE architecture 56Kbps.
