DESCRIPTION
The Philips Semiconductors PDI1394P11A is an IEEE1394-1995 compliant Physical Layer interface. The PDI1394P11A provides the analog physical layer functions needed to implement a three port node in a cable-based IEEE 1394–1995 network. Additionally, the device manages bus initialization and arbitration cycles, as well as transmission and reception of data bits. The Link Layer Controller interface is compatible with both 3V and 5V Link Controllers. While providing a maximum transmission data rate of 200 Mb/s, the PDI1394P11A is compatible with current 100 Mb/s Physical Layer ICs. The PDI1394P11A is available in the LQFP64 package.

FEATURES
• 3 cable interface ports
• Supports 100Mb/s and 200Mb/s transfers
• Interfaces to any 1394 standard Link Layer Controller
• 5V tolerant I/Os with Bus Hold Circuitry
• Single 3.3V supply voltage
• Arbitrated (short) Bus Reset (1394a feature)
• Fully compatible with existing 100 Mbps Phys on the market
• Prevents a TpBias voltage driven into a non-powered PDI1394P11A from erroneously powering up the part
