Description
PCI interface that is compliant with PC99, PCI 2.2 and Power Management 1.1
Internet Phones (VoIP), Software modems, ISDN TAs and other applications that require a low cost PCI 2.2 interface with bus mastering
The Tiger320 has been designed to enable easy implementation of low cost PCI interfacing solutions for general-purpose requirements. Typical examples are Internet phones where the Tiger320 would be partnered with a SLIC, software modems where the Tiger320 would be partnered with a DAA and codec, ISDN modems (terminal adaptors) where the Tiger320 would be partnered with an ISDN AFE and hard analog modems where the Tiger320 could enable a 3.3V PC99 solution. Two interfaces are provided, the PIB (Peripheral Interface Bus) and the TDM/IOM2/PCM highway serial interface. The PIB consists of an 8 bit data port, 4 address line control signals (read, write, reset) and 8 aux lines that can be configured for chip selects, interrupts etc. If the chip to be interfaced has an address and data bus this is the interface that would be used. An example of this would be a UART or a hard modem chip set.
The TDM interface can be used for interfacing most popular SLIC, ISDN, Analog modem DAAs and audio codecs. Bus mastering can be used to transfer data to the main memory of the host PC. PCI interfaces that both meet the PCI specification and work across the full range of PC systems are a significant design challenge. The Tiger320 leverages the design expertise of the very successful Tiger300, Tiger100APC and Tiger600 chips and provides a PCI interface that meets the requirements of PCI 2.2 and the Power management 1.1 specifications. PCI subsystem vendor and subsystem IDs are set by pull up/down resistors, this provides a significant cost saving in comparison with the expensive EEPROM approach that is used by other vendors. In addition the Tiger320 provides a crystal oscillator cell that can be used to implement a clock source for codecs etc. This oscillator is not required by any circuitry of the Tiger320.
