APPENDIX C—Si3008 SUPPLEMENT
Si3008 Introduction
The Si3008 is a small form factor line-side device with a
reduced peripheral component count. The Si3008
meets the telephone network compatibility requirements
for North America and many other countries. This
appendix describes the Si3008 and its use with the
Si2493/57/34/15/04 ISOmodem
®
. The Si3008 features
are described and compared to those of the Si3018/10,
and a reference design is presented. Si3008 layout
guidelines and a sample layout are also included.
Finally, a prototype bring-up guide is presented for
Si3008-based designs.
Si3008 Capabilities and Limitations
Supported Features
The Si3008 uses Silicon Laboratories' patented
isolation technology to communicate with the Si2401
ISOmodem and provide high-voltage isolation. The
Si3008 meets the telephone network interface
requirements of the countries listed in Table 105 and
provides up to 6 kV of surge performance with Y2
isolation capacitors. The Si2493/57/34/15/04/3008
chipset meets all global requirements for EMI, EMC,
and safety if proper layout guidelines are followed. The
information presented here is a summary. For complete
details, see the Si2493/57/34/15/04/Si3008 datasheet.
