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
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.
