Geode™ CS4210 IEEE 1394 OHCI Controller

General Description

The National Semiconductor

Geode™ CS4210 is a PCI-

based IEEE 1394 OHCI (Open Host Controller Interface)

controller. The CS4210 provides an implementation of the

IEEE 1394 Link Layer functionality according to the pro-

gramming model defined by 1394 OHCI Specification Ver-

sion 1.0. It supports high speed serial communication up to

400 Mbits per second.

The CS4210 is an implementation of the link layer protocol

of the IEEE 1394 high speed serial bus, with additional fea-

tures to support the transaction and bus management lay-

ers. The CS4210 also includes DMA engines for high

speed performance data transfer and a host PCI bus inter-

face. Perfect for use in PC, set-top box, thin client, and

WebPAD™ system applications.

The CS4210 supports two types of data transfers: asyn-

chronous and isochronous.

The CS4210 provides an external IEEE 1394 physical layer

device interface. The CS4210’s physical layer interface

(PHY-Link) is compatible with the Geode™ CS4103 and

other IEEE 1394 physical layer devices.
