Description
The Si2400URT-EVB evaluation board provides the
system designer an easy way to evaluate the Si2400
ISOmodem
motherboard and power supply, an RS-232 interface
and USB, other ease-of-use features, and a complete,
removable modem module on a daughter card. (A
functional block diagram of the Si2400URT-EVB is
shown below.) The Si2400 ISOmodem is a complete
controller-based modem chipset with an integrated and
programmable direct access arrangement (DAA) that
meets global telephone line requirements. Available as
two 16-pin small outline (SOIC) packages, the Si2400
ISOmodem eliminates the need for a separate DSP
data pump, modem controller, memories, analog front
end (AFE), isolation transformer, relays, opto-isolators,
and a 2- to 4-wire hybrid. The Si2400 is ideal for
embedded modem applications due to its small board
area,
consumption, and global compliance. The Si2400URT-
EVB provides an RJ-11 jack and a DB9 connector for
interfacing the Si2400URT-EVB to the phone line and a
PC or data terminal serial port. This allows the Si2400
ISOmodem to operate as a serial modem for
straightforward evaluation. To evaluate the Si2400
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 Si2400 ISOmodem directly to a target
system. The EVB also provides test points for access to
the analog input and analog output. These interfaces
can be used to evaluate the Si2400 PCM and voice
modes. Given that any of the GPIO pins may be used
as an audio input, the EVB provides access to all GPIO
pins.
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 or
not the USB interface is used). The Si2400URT-EVB
can drive an external speaker for call monitoring, or a
piezoelectric speaker can be mounted directly on the
board in the space provided.
