Description
The Si2401FS10-EVB evaluation board provides the
system designer an easy way of evaluating the Si2401
ISOmodem
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 Si2401FS10-EVB is
shown below.) The Si2401 ISOmodem is a complete
controller-based modem chipset integrating Silicon
Labs’ third-generation, globally-programmable direct
access arrangement (DAA). Available as two 16-pin
small outline (SOIC) packages, the Si2401 ISOmodem
eliminates the need for a separate DSP data pump,
modem
transformer, relays, opto-isolators, and a 2- to 4-wire
hybrid. The Si2401 is ideal for embedded modem
applications due to its small board area, controller-
based architecture, low power consumption, and global
compliance. The Si2401FS10-EVB provides an RJ-11
jack for interfacing to the phone line and a DB9 or USB
connector for interfacing the Si2401FS10-EVB to a PC
or data terminal serial port. This allows the Si2401
ISOmodem to operate as a serial modem for
straightforward evaluation. To evaluate the Si2401
ISOmodem in an embedded system, the daughter card
can be used independently or with the motherboard.

A direct access header (JP3) is available on the
motherboard to bypass the RS-232 transceivers and
connect the Si2401 ISOmodem directly to a target
system.
Power is supplied through a screw terminal (J3) or a
standard 2 mm power jack (J4). An onboard rectifier,
filter, and voltage regulator allow the power input to be
7.5–13 V ac or dc (either polarity). Alternatively, power
can be supplied through the USB interface (whether the
USB or an RS232 interface is used). The Si2401FS10-
EVB can drive an external speaker for call monitoring,
or a piezoelectric speaker can be mounted directly on
the board in the space provided.
