Description

The global Si2493/57/34/15/04-EVB evaluation board

provides the system designer an easy way of evaluating

the Si2493/57/34/15/04 ISOmodem

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

controller-based modem chipset with an integrated and

programmable direct access 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 device, the Si2493/57/

34/15/04 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 Si2493/57/34/15/04 is ideal for

embedded modem applications due to its small board

area,

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 (JP3) is available

on the motherboard to bypass the RS-232 transceivers

and

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 (J3) or a standard

2 mm power jack (J4). 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

piezoelectric speaker mounted directly on the board.

Please note that the PCM interface, parallel interface,

and EEPROM are available on the FT only. See

"1.7.EVB Part Numbers" on page 5 for ISOmodem EVB

options.
