„ FAX mode capabilities:
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 µDSP-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.

a. Power Down Mode
Host can instruct modem system to enter power down
mode by “AT*P” command. There are two ways to wake
µDSP.
(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:

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”.

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.
