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.
