FEATURES
2.0
The PDI1394L21, Philips Semiconductors Full Duplex 1394
Audio/Video (AV) Link Layer Controller, is an IEEE 1394–1995
compliant link layer controller featuring 2 embedded AV layer
interfaces. The AV layers are designed to pack and un-pack
application data packets for transmission over the IEEE 1394 bus
using isochronous data transfers. Because of its full duplex
architecture, the PDI1394L21 is capable of receiving and
transmitting isochronous data during the same bus cycle. Two 8 bit
AV ports, each with its own buffer (FIFO), receive and output
isochronous data for transmission and reception of bus packets.
Each port can be configured to receive or transmit, however, the
other port always performs the opposite function. Half duplex
operation is also permitted.
DESCRIPTION
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. An 80C51 compatible byte-wide host interface is provided
for internal register configuration as well as performing
asynchronous data transfers.
The PDI1394L21 is powered by a single 3.3V power supply and the
inputs and outputs are 5V tolerant. It is available in the LQFP100
and TQFP100 packages.
