1 Introduction

1.1

Description

The Texas Instruments TSB12LV26 is a PCI-to-1394 host controller compatible with the latest

PCI Local Bus, PCI

Bus Power Management Interface, IEEE 1394-1995, and 1394 Open Host Controller Interface Specification. The

chip provides the IEEE 1394 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 Open Host Controller Interface Specification (OHCI) and IEEE proposal 1394a specification,

internal control registers are memory-mapped and nonprefetchable. The PCI configuration header is accessed

through configuration cycles specified by PCI, and provides Plug-and-Play (PnP) compatibility. Furthermore, the

TSB12LV26 is compliant with the

PCI Bus Power Management Interface Specification, per the PC 99 Design Guide

requirements. TSB12LV26 supports the D0, D2, and D3 power states.

The TSB12LV26 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, deep FIFOs are provided

to buffer 1394 data.

The TSB12LV26 provides physical write posting buffers and a highly tuned physical data path for SBP-2 performance.

The TSB12LV26 also provides multiple isochronous contexts, multiple cacheline burst transfers, advanced internal

arbitration, and bus holding buffers on the PHY/link interface.

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

33 MHz.
