Tiger320 PCI 2.2 communications controller chip

General Description

The Tiger320 by TigerJet is a PCI communications controller that implements the PCI 2.2 specification (PCI SIG tested and certified). In addition it also implements the Power Management 1.1 specification. By implementing PCI 2.2 and PM 1.1 the Tiger320 meets the requirements of Microsoft WHQL and enables boards that use the Tiger320 to be eligible for the Microsoft Windows Logo (WHQL).

Applications that use the Tiger320 in high volume production today include software modems, ISDN terminal adaptors (modems), telephone interfaces (for VoIP). In addition the Tiger320 has been chosen for many other varied applications.

For interfacing to many popular communications chips such as DAAs, SLICs, ISDN AFEs etc., the Tiger320 has a TDM / IOM2 / GCI / PCM Highway serial interface. Data from the serial interface can be written to main system memory using PCI bus mastering. This enables data transfers to take place without CPU intervention. After a predetermined number of bytes has been transferred the Tiger320 can be programmed to generate an interrupt. 

The Peripheral Interface Bus (PIB) provides byte wide data, 4 address lines, 8 control lines (AUX pins), read, write and reset. The PIB is ideal for interfacing UARTs, hard modems and a wide range of peripheral chips that have address and data lines.

All 16 bits of the PCI subsystem vendor ID is programmable using resistors, this represents a significant cost saving over the EEPROM devices used by other products.
