Si2401FS10-EVB
EVALUATION BOARD FOR THE Si2401 WITH A
UART INTERFACE
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.
Description
The Si2401FS10-EVB evaluation board provides the
system designer an easy way of evaluating the Si2401

ISOmodem . The Si2401FS10-EVB consists of a
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.

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 controller, memories, codec, isolation
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

2.3. Jumper Settings
Check all jumper settings on the Si2401FS10-EVB before applying power. Figure 1 shows the standard factory
jumper settings. These settings configure the Si2401FS10-EVB for RS-232 serial operation. Any standard terminal
program configured to communicate through a PC COM port can be used to communicate with the Si2401FS10-
EVB. To connect the modem directly into an embedded system with LVCMOS/TTL levels, install JP8 to disable
both the RS-232 and USB interfaces. Connection to the embedded system can be made to JP-3. Place a jumper
on JP13 to enable the onboard speaker, LS1.

Si2401FS10-EVB
To make a modem connection, type “ATDT(called
modem phone number)<CR>.” Once the connection is
established, a “c” message appears, indicating the two
modems are in the data mode and communicating.
Typing on one terminal should appear on the other
terminal. To return to the command mode without
interrupting the connection between the two modems,
type “+++.” Approximately two seconds later, “O” will
appear. The modem is now in command mode and will
accept “AT” commands. To return to data mode, type
“ATO.” The modem resumes the data connection and
no longer accepts AT commands. Type “ATH” to
terminate the data connection.
2.4. Power Requirements
The Si2401FS10-EVB has an onboard diode bridge,
filter capacitor, and voltage regulator. Power can be
supplied from any source capable of providing 7.5–13 V
dc or 7.5–13 V peak ac and at least 100 mA. (Additional
current may be required if a speaker is connected for
monitoring call progress tones.) Power may be applied
to the Si2401FS10-EVB through the screw terminals
(J3) or the 2 mm power jack (J4). The onboard full-wave
rectifier and filter ensure that the correct polarity is
applied to the Si2401FS10-EVB. Daughter card power
is supplied through voltage regulator U2 and is factory-
set at 3.3 V. Power is also supplied by the USB cable
and can be used regardless of whether the modem is
configured for the USB, RS-232, or direct interface
mode. Daughter card current can be measured by
connecting an ammeter between JP7 pins 1 and 2.
These pins must always be connected. Failure to
connect pins 1 and 2 of JP7 through either a jumper or a
low-impedance ammeter may result in damage to the
Si2401FS10-EVB.
3. Si2401FS10-EVB Functional
Description
The Si2401FS10-EVB is a multipurpose evaluation
system. The modem daughter card illustrates the small
size and small number of components required to
implement an entire controller-based modem with
global telecommunications compatibility. The daughter
card can be used independently of, or in conjunction
with, the motherboard. The motherboard adds features
that enhance the ease of evaluating the many
2.5. Terminal and Line Connections
The Si2401 can be tested as a standard serial data
modem by connecting the Si2401FS10-EVB to a
personal computer or other data terminal equipment
(DTE), phone line, and power. Connect a PC, RS-232,
or USB interface to the Si2401FS10-EVB with the
appropriate cable. The RS-232 transceivers on the EVB
can communicate with the DTE at rates of up to 1 Mbps.
Any standard terminal program, such as HyperTerminal
or ProComm, running on a PC can communicate with
the Si2401FS10-EVB. Configure the terminal emulation
program to 2400 bps, 8 data bits, no parity, one stop bit,
and hardware flow control. Also, be sure to disable
linefeeds with carriage returns. Connect the RJ-11 jack
on the Si2401FS10-EVB to an analog phone line or
telephone line simulator, such as a Teltone TLS 5.

capabilities of the Si2401 ISOmodem .
3.1. Motherboard
The motherboard provides a convenient interface to the
Si2401DC (daughter card). The versatile power supply
allows for a wide range of ac and dc voltages to power
the board. RS-232 transceivers and a DB9 connector
allow the Si2401FS10-EVB to be easily connected to a
PC or other terminal device. Jumper options allow direct
access to the LVCMOS/TTL level serial inputs to the
Si2401, bypassing the RS-232 transceivers or USB
interface. This is particularly useful for directly
connecting the Si2401 to embedded systems.
The Si24xxFS10-EVB motherboard connects to the
daughter card through two connectors, JP1 and JP2.
JP1 is an 8x2 socket providing connection to all Si2401
digital signals and regulated 3.3 V power for the Si2401.
The Si2401 digital signals appearing at JP1 (daughter
card interface) are LVCMOS- and TTL-compatible. The
Si2401DC must be powered by 3.3 V. The motherboard
is factory-configured for 3.3 V with JP7 pins 1 and 2.
JP2 is a 4x1 socket providing connection between the
daughter card and the RJ-11 phone jack.
2.6. Making Connections
With the terminal program properly configured and
running, apply power to the Si2401FS10-EVB. Type
“AT<CR>”, and the modem should return “O” indicating
the modem is working in the command mode and
communicating with the terminal. If the “O” response is
not received, try resetting the modem by pressing the
manual reset switch (S1); then type “AT<CR>” again.
To take the modem off-hook, type “ATDT<CR>.” The
modem should go to the off-hook state, draw loop
current, and respond with a “t”, indicating a dial tone
detection. Typing any characters makes the modem
hang up (go on-hook) and stop drawing loop current.

3.1.8. Direct Access Interface
The USB cable connects to J5 on the motherboard and
provides both data and power. Installing a jumper on
JP5 enables the USB interface and disables the RS-232
interface. The USB interface is provided by U5. A USB
driver for this chip is available for most PC and MAC
operating systems on the CD.
The motherboard supplies power through J3, J4, or
USB, power-on reset, and an RJ-11 jack for the modem.
The direct access interface (JP3) is used to connect the
motherboard to an embedded system. JP3 provides
access to all Si2401 signals available on the daughter
card. It is necessary to install a jumper on JP8 to disable
both the RS-232 and USB interface and prevent signal
contention. Leave the jumper between JP7 pins 1 and
2. Figure 3 illustrates the jumper settings required for
the direct access mode using the motherboard.

(JP1, pin 13), must be held low for at least 5.0 ms after
power is applied and stabilized and returned high with a
rise time less than 100 ns to ensure that the device is
properly reset.
3.1.10. Amplifier (LM386)
3.2.2. Crystal Requirements
The audio amplifier circuit consists of U10 (LM386),
C20, R3, R4, C21, C22, C23, R5, C24, and an optional
loudspeaker, LS1. The LM386 has an internally-set
voltage gain of 20. R3 and R4 provide a voltage divider
to reduce the AOUT signal to prevent overdriving the
LM386. C20 provides dc blocking for the input signal
and forms a high-pass filter with R3+R4, while R4 and
C21 form a low-pass filter. These four components limit
the bandwidth of the AOUT signal. C22 provides high-
frequency power supply bypassing for the LM386 and
should be connected to a hard ground and located very
close to the amplifier’s power supply and ground pins.
C23 and R5 form a compensation circuit to prevent
oscillation of the high-current PNP transistor in the
LM386 output stage on negative signal peaks. These
oscillations can occur between 2–5 MHz and can pose
a radiation compliance problem if C23 and R5 are
omitted. C24 provides dc blocking for the output of the
Clock accuracy and stability are important in modem
applications. To ensure reliable communication
between modems, the clock must remain within
±100 ppm of the design value over the life of the
modem. The crystal selected for use in a modem
application must have a frequency tolerance of less
than ±100 ppm for the combination of initial frequency
tolerance, drift over the normal operating temperature
range, and five-year ageing. Other considerations, such
as production variations in PC board capacitance and
the tolerance of loading capacitors, must also be taken
into account.
3.2.3. Protection
The Si2401FS10-EVB meets or exceeds all FCC and
international PTT requirements and recommendations
for high-voltage surge and isolation testing without any
modification. The protection/isolation circuitry includes
C1, C2, C8, C9, FB1, FB2, and RV1. The PCB layout is
also a key “component” in the protection circuitry. The
Si2401FS10-EVB provides isolation to 3 kV. Contact
Silicon Laboratories for information about designing to
higher levels of isolation.
