General Description
The Modem Chip IP568X is a highly integrated, low-cost, high performance, low-power, a full-function modem solution. IP568X implements V.90 to achieve Internet connection rates up to 56Kbps, supporting existing V.34 data mode, video-ready interface, Class 1 FAX, TAM (Telephone Answer Machine) and Speakerphone functions. IP568X's I/O pins allow designer to easily control DAA or design modem for special application. IP568X is a DSP-based chip designed specifically for modem application, and it performs high MIPS operations such as V.90, V.34 and V.32 modulation. IP568X provides a serial interface for connecting to codec. IP568X uses high quality design to optimize modem configuration for line condition and provide reliable connection with connection rate ranging from 300bps up to 56Kbps. IP568X is the best choice for designing a modem.

System Configuration
a. Power Down Mode Host can instruct modem system to enter power down mode by "AT*P" command. There are two ways to wake DSP. (1) Power off then power on modem (2) Negative pulse is occurred at input pins "RI\" of IP568X b. Re-flash Program Memory (Download New code) By setting C0H.0 (reset state: 0), system can switch program and data memory. If system uses FLASH memory as program memory, we can use this function to replace program code by loading download program to data memory then swapping external data memory and external program memory. For example, SETB C0H,0 LJMP 0000H In this modem system, modem provides a AT command for download function. When users get new code and want to upgrade current program code, the following procedure can be used: ATxxxx (Issue Download command) Ready (Modem response "Ready") Send ASCII File (Choose send ASCII file in communication software & send new code to modem) Wait moment (download program) . . (Waiting) . OK (When download procedure is complete, modem will response OK.) Note: When modem is in download mode, don't turn off power. c. DAA (Data Access Arrangement) & NCU (network Control Unit) The modem chip provides standard serial interface for Codec. IP568X can support traditional code plus transformer-based NCU circuit and advance silicon DAA. For further information, please contact technical supporting engineer. d. AT command IP568X modem supports Data, Fax and Voice function. All functions are controlled by AT command. IC ACE will provide source code of AT command part for customer modification. Please refer to the document " User's Manual & AT command set".

e. V.44 V.44 New compression scheme that compresses HTML text for faster web downloads. IP568X has already combined the V.44 function into its internal ROM. That means, IP568X don't need to add any extra components for this advance function.
