Tiger560
Advance Information
General Description
VoIP (Internet Phone) applications are becoming increasing popular as VoIP can
provide free or low-cost calling worldwide. Early users of VoIP have attempted to use
the existing PC sound card and have suffered poor call quality due to echoes and
other problems.
To provide a VoIP experience that is the same as using a regular phone and
eliminate the poor call quality that results from using the PC sound card, TigerJet has
developed the Tiger560 USB controller that enables a regular phone, handset or
headset to be interfaced to the USB port on the PC. With the Tiger560 OEMs can
quickly bring to market a family of low cost high quality VoIP products.
The Tiger560 USB registers are compatible with the Microsoft USB audio driver and
the Tiger560 is able to use the Microsoft written and supported driver directly. For
many audio applications such as phone handsets or headsets, no additional software
drivers are required. By using the standard Microsoft USB audio driver all popular
Internet Telephony applications are supported and users will be able to make free or
low cost calls with the same user experience as using a regular phone.
For phone handset or headset to USB applications, a low cost 8bit u-law “telephone”
codec can be directly interfaced to the Tiger560 to provide a very highly integrated
and low cost solution. For this type of product only the Microsoft USB audio driver is
required.
For regular phone to USB applications, a SLIC (subscriber line interface chip) can be
interfaced to the Tiger560. The SLIC interfaces to the phone via the standard RJ-11
connector. The Tiger560 provides the USB interfacing and control. Reference drivers
are available that enable the phone to ring, provide on hook/off hook detection and
implement DTMF decode.
The Tiger560 incorporates an SPI interface, TDM/IOM2/GCI serial interface and a
peripheral Interface Bus (PIB). The PIB has byte wide data, 6 address lines, 8
configurable control lines and read and write lines.
