Si2493/57/34/15/04 Global ISOmodem-EVB Evaluation Board Rev 5.0 for the Si2493/57/34/15/04 ISOmodem with UART and SPI Interfaces Description A direct access header (J103) is available on the motherboard to bypass the RS-232 transceivers and The global Si2493/57/34/15/04-EVB evaluation board connect the Si2493/57/34/15/04 ISOmodem directly to Rev 5.0 provides the system designer an easy way of a target system. evaluating the Si2493/57/34/15/04 ISOmodem . The An on-board rectifier, filter, and voltage regulator allow Si2493/57/34/15/04-EVB consists of a motherboard the power input to be 7.513 V ac or dc (either polarity) with a power supply, an RS-232 and USB interface, supplied through a screw terminal (J8) or a standard other ease-of-use features, and a complete removable 2mm power jack (J9). Alternatively, power can be modem module on a daughter card. (A functional block supplied through the USB interface (whether the USB or diagram of the Si2493/57/34/15/04-EVB is shown RS232 interface is used). The evaluation board can below.) The Si2493/57/34/15/04 ISOmodem is a drive an external speaker for call monitoring or the complete controller-based modem chipset with an speaker mounted directly on the board. Please note that integrated and programmable direct access the PCM interface, parallel interface, and EEPROM are arrangement (DAA) that meets global telephone line available on the 24-pin FT only. See1.7.EVB Part requirements. Available as a combination of one 16-pin Number on page 8 for ISOmodem EVB options. small line-side device and one 24-pin or 16-pin system- side device, the Si2493/57/34/15/04 ISOmodem Features eliminates the need for a separate DSP data pump, modem controller, memories, codec, isolation The Si2493/57/34/15/04-EVB includes the following: transformer, relays, opto-isolators, and a 2- to 4-wire Dual RJ-11 connection to phone line hybrid. The Si2493/57/34/15/04 is ideal for embedded RS-232 and USB interface to PC modem applications due to its small board area, controller-based architecture, low power consumption, Speaker for call monitoring and global compliance. The Si2493/57/34/15/04-EVB Direct access to Si2493/57/34/15/04 for provides an RJ-11 jack (for interfacing the embedded application evaluation Si2493/57/34/15/04-EVB to the phone line), and USB Easy power connection to common 7.5 V13.5 V and RS232 serial ports for interfacing to a PC or data power supplies or USB port. terminal. This allows the ISOmodem to operate as a 9 V ac adaptor serial modem for straightforward evaluation of the Simple installation and operation Si2493/57/34/15/04. To evaluate the Si2493/57/34/15/04 ISOmodem in an embedded EEPROM (24-pin FT only) system, the daughter card can be used independently RS232 lines status display on LEDs. of or with the motherboard.
