10. Si2457FT18-EVB Modem Board
The Si2457FT18-EVB Modem Board includes a complete controller-based modem chipset with an integrated and
programmable direct access arrangement (DAA) that meets global telephone line requirements. This board is a
complete modem solution suited for use in an embedded system. The modem board requires a 3.3 V supply
capable of providing at least 35 mA and communicates with the system via LVCMOS/TTL-compatible digital
signals on JP1. When using the Embedded Modem Development Kit, the power supply and communication signals
are provided by the C8051F120 Target Board through the AB3 Modem Adapter Board. The RJ-11 jack is
connected via JP2. See Section 9.3 for JP1 and JP2 pin descriptions.
