Description

The National Semiconductor® Geode™ CS4210 is a PCIbased IEEE 1394 OHCI (Open Host Controller Interface) controller. The CS4210 provides an implementation of the IEEE 1394 Link Layer functionality according to the programming model defined by 1394 OHCI Specification Version 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 features to support the transaction and bus management layers.

The CS4210 also includes DMA engines for high speed performance data transfer and a host PCI bus interface. Perfect for use in PC, set-top box, thin client, and WebPAD™ system applications.

The CS4210 supports two types of data transfers: asynchronous 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.
