Description

The global Si2493/57/34/15/04-EVB evaluation board Rev 5.0 provides the system designer an easy way of evaluating the Si2493/57/34/15/04 ISOmodem?. The Si2493/57/34/15/04-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 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 a combination of one 16-pin small line-side device and one 24-pin or 16-pin systemside 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, controller-based architecture, low power 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.
