GENERAL DESCRIPTION
The Z02201 is a synchronous single-chip modem solution
that provides a means to construct a V.22bis modem capable
of 2400 bps full duplex over dial-up lines. The Z02201 is
specifically designed for use in embedded modem
applications where space, performance, and low power
consumption are key requirements.
Operating over the Public Switched Telephone Network
(PSTN), the Z02201 meets the modem standards for
V.22bis, V.22, V.23, V.21, Bell 212A, and Bell 103.
A typical modem application can be made by simply adding
a control microprocessor (host), phone-line interface, and
DTE interface.
The Z02201 performs HDLC framing at all speeds. This
capability eliminates the requirement for an external Serial
Input/Output (SIO) device for Data Terminal Equipment
(DTE) in products incorporating error control.
