Offered as a chipset with the Si2493 system-side device and the CLKOUT/EECS/A0 3 22 ESC/D3 Si3018 line-side device, the ISOmodem utilizes Skyworks Solutions FSYNC/D6 4 21 VD3.3 VD3.3 5 20 GND patented Direct Access Arrangement (DAA) technology to provide a 6 19 VDB GND programmable telephone line interface with an unparalleled level of 7 18 VDA SDI/EESD/D2 integration. This compact solution eliminates the need for a separate DSP, SS/RTS/D7 8 17 RI/D1 16 MISO/RXD/RD 9 INT/DO modem controller, codec, transformer, relay, opto-isolators, clocking 15 AOUT/INT MOSI/TXD/WR 10 crystal, and 24 wire hybrid. Available with a system-side packaging option 14 C1A SCLK/CTS/CS 11 of either a 16-pin SOIC or a 24-pin TSSOP, the Si2493 is ideal for 13 RESET 12 C2A embedded modem applications due to its flexibility, small footprint, and minimal external component count.
