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.
