SI2493 - Brand New SILICON LABS IC Chips
-
Description
The Si2493 is an ISOmodem chipset that serves as a controller-based modem with a programmable direct access arrangement (DAA) that meets global telephone line requirements. It includes a 16-pin small line-side device and a 24-pin or 16-pin system-side device that does not require a separate DSP data pump, modem controller, memories, codec, isolation transformer, relays, opto-isolators, or a 2- to 4-wire hybrid. It is suitable for embedded modem applications due to its small board area, controller-based architecture, low power consumption, and global compliance. The global Si2493/57/34/15/04-EVB evaluation board Rev 5.0 provides the system designer with a more accessible way to evaluate the Si2493 modem.

Application Scenarios
The Si2493/57/34/15/04-EVB serves as an evaluation board that provides an RJ-11 jack for interfacing the Si2493 modem to the phone line, and USB and RS232 serial ports for interfacing to a PC or data terminal. This 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 daughter card can be used independently or with the motherboard for evaluating the Si2493 in an embedded system.
Comparison
Advantages- 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
- Small board area and controller-based architecture make it ideal for embedded modem applications
- Global compliance ensures it meets all global telephone line requirements
Disadvantages- The Si2493/57/34/15/04-EVB may not be suitable for use in all systems and configurations
- The evaluation board may not be as cost-effective as other evaluation methods
