Global Voice ISOmodem-EVB

Evaluation Board for the Si2494/39/38/37/36/35/29/19/18/17

ISOModem

Description

The Global Voice ISOmodem EVB evaluation board

provides the system designer with an easy way of

evaluating the ISOmodem



. The Voice ISOmodem EVB

consists of a motherboard with a complete removable

daughter card

The Voice ISOmodem is a complete controller based

modem chipset with an integrated and programmable

direct access arrangement (DAA) that meets the global

telephone line requirements. It is available in a 24-pin or

38-pin system side device and a 16-pin line side device.

The hardware versions at the time of publication are:

 Voice Mother Board Si24xxVMB Rev 2.0

 Modem Daughter Card Si24xx2G-DC Rev 2.0

 Modem Daughter Card Si24xx2G-QFN38-DC Rev

1.0

The voice daughter card is populated with the correct

ISOmodem system side chip (Si2494/39/38/37/36/35/

29/19/18/17) and the correct line side DAA chip, the

Si3018 to suit the voice applications.

The ISOmodem eliminates the need for a separate DSP

data pump, modem controller, memories, codec,

isolation transformers, relays, opto-isolators and a 3-4

wire hybrid. The ISOmodem is ideal for embedded

modem and voice applications due to its small board

area, controller based architecture, low power

consumption and global compliance.

An onboard 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 Power Source Selection in automatic, while the

signaling port is selected by a jumper (JP23).

The evaluation board audio power amplifier can drive

an external speaker for either call progress monitoring

or speakerphone function. A small onboard speaker,

suitable for call progress monitoring, is installed.

Please note that fax modem versions listed in the title

require a software driver in order to implement fax send/

receive functionality. The driver must be compliant with

the Silicon Labs ISOmodem and with applicable ITU-T

standards (e.g., T.30, T.31, T.4 and T.6) Contact Silicon

Labs for details.

Features

This evaluation board includes the following:

 Socketed module with the modem chipset

 USB or asynch RS232 Serial Interface

 RJ11 connection to the phone line

 Onboard relay-excludable RJ11 connection

 RS232 and USB interface to the PC

 Direct access to the ISOmodem signals for

embedded system evaluation

 Power from a provided 8.5–13.5 V dc power supply

or from the USB port

 Handset connector (J1)

 Onboard hookswitch

 External hookswitch connector

 Jumper matrix that allows any handset wiring

scheme to work with this board

 Onboard speakerphone microphone

 RCA jack connector to an optional off-board

speakerphone electret microphone

 Selectable and adjustable electret power supplies for

both handset and speakerphone microphones

 Onboard 300 mW audio power amplifier (into a 4 

load) for driving either onboard or external speaker.

 Onboard voice coil driven loudspeaker for call

monitoring

 LED display of all RS232 signals
