PRELIMINARY DATA SHEET

PD72870,72871

IEEE1394 1-CHIP OHCI HOST CONTROLLER

MOS INTEGRATED CIRCUIT

The

PD72870, 72871 are the LSIs which integrated OHCI-Link and PHY function into a single chip.

The

PD72870, 72871 comply with the P1394a draft 2.0 specifications and the OpenHCI IEEE1394 1.0 and work

up to 400 Mbps.

These make design so compact for PC and PC card application.

FEATURES

• Compliant with Link Layer Services as defined in 1394 Open Host Controller Interface specification release 1.0

• Compliant with Physical Layer Services as defined in P1394a draft 2.0 (Data Rate 100/200/400 Mbps)

3-port :

PD72870
