Description
The global Si2493/57/34/15/04-EVB evaluation board
Rev 5.0 provides the system designer an easy way of
evaluating the Si2493/57/34/15/04 ISOmodem
Si2493/57/34/15/04-EVB consists of a motherboard
with a power supply, an RS-232 and USB interface,
other ease-of-use features, and a complete removable
modem module on a daughter card. (A functional block
diagram of the Si2493/57/34/15/04-EVB is shown
below.) The Si2493/57/34/15/04 ISOmodem is a
complete controller-based modem chipset with an
integrated
arrangement (DAA) that meets global telephone line
requirements. Available as a combination of one 16-pin
small line-side device and one 24-pin or 16-pin system-
side
eliminates the need for a separate DSP data pump,
modem
transformer, relays, opto-isolators, and a 2- to 4-wire
hybrid. The Si2493/57/34/15/04 is ideal for embedded
modem applications due to its small board area,
controller-based architecture, low power consumption,
and global compliance. The Si2493/57/34/15/04-EVB
provides an RJ-11 jack (for interfacing the Si2493/57/
34/15/04-EVB to the phone line), and USB and RS232
serial ports for interfacing to a PC or data terminal. This
allows the ISOmodem to operate as a serial modem for
straightforward evaluation of the Si2493/57/34/15/04. To
evaluate the Si2493/57/34/15/04 ISOmodem in an
embedded system, the daughter card can be used
independently of or with the motherboard.

A direct access header (J103) is available on the
motherboard to bypass the RS-232 transceivers and
connect the Si2493/57/34/15/04 ISOmodem directly to
a target system.
An on-board rectifier, filter, and voltage regulator allow
the power input to be 7.5–13 V ac or dc (either polarity)
supplied through a screw terminal (J8) or a standard
2 mm power jack (J9). Alternatively, power can be
supplied through the USB interface (whether the USB or
RS232 interface is used). The evaluation board can
drive an external speaker for call monitoring or the
speaker mounted directly on the board. Please note that
the PCM interface, parallel interface, and EEPROM are
available on the 24-pin FT only. See "1.7.EVB Part
Numbers" on page 8 for ISOmodem EVB options.
