1394 enhanced AV link layer controller
PDI1394L40
1.0 FEATURES
•
IEEE1394a and IEEE1394–1995 Standard Link Layer Controller
•
Hardware Support for the IEC61883 International Standard of
Digital Interface for Consumer Electronics
2.0 DESCRIPTION
The PDI11394L40, Philips Semiconductors Full Duplex 1394
Audio/Video (AV) Link Layer Controller, is an IEEE 1394a–2000
compliant link layer controller featuring 2 embedded AV layer
interfaces.
The application data 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 MPEG–2 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.
