NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150.

The PDI1394L40, Philips Semiconductors Full Duplex 1394 Audio/Video (AV) Link Layer Controller, is an IEEE 1394a2000 compliant link layer controller featuring 2 embedded AV layer interfaces.

The application data of PDI1394L40 is packetized according to the IEC 61883 International Standard of Interface for Consumer Electronic Audio/Video Equipment. Both AV layer interfaces are byte-wide ports capable of accommodating various MPEG2 and DVC codecs. A flexible host interface is provided for internal register configuration as well as performing asynchronous data transfers.

Both 8 bit and 16 bit wide data paths, as well as multiplexed/non-multiplexed access modes are supported.

The PDI1394L40 is powered by a single 3.3 V power supply and the inputs and outputs are 5 V tolerant. It is available in the LQFP144 package.
