description

The Texas Instruments OHCI-Lynx is a PCI-to-1394 host controller compatible with the latest PCI, IEEE1394,

and 1394 OHCI 1.00 specifications. The chip provides the IEEE1394 link function, and is compatible with serial

bus data rates of 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s.

As required by the 1394 OHCI Specification, internal control registers are memory mapped and

non-prefetchable. The PCI configuration header is accessed through configuration cycles specified by PCI, and

provides Plug-and-Play (PnP) compatibility. Furthermore, the OHCI-Lynx is compliant with the PCI Power

Management Specification, per the PC ′98 requirements.

The OHCI-Lynx design provides PCI bus master bursting, and is capable of transferring a cacheline of data at

132 Mbytes/s after connection to the memory controller. Since PCI latency can be large even on a PCI Revision

2.1 system, deep FIFOs are provided to buffer 1394 data.

Physical write posting buffers are provided to enhance serial bus performance, and multiple isochronous

channels are provided for simultaneous operation of real-time applications. The OHCI-Lynx also provides bus

holding buffers on the phy interface for simple and cost effective single capacitor isolation.

An advanced CMOS process is used to achieve low power consumption while operating at PCI clock rates up

to 33 MHz.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
