Description
The CXD1948R is a Link Layer LSI conforming to the IEEE1394 serial bus standard. During transmission, the MPEG2 transport stream is time stamped, transformed to IEEE1394 format and sent to the IEEE1394 Phy IC.
During reception, the signal from IEEE1394 is kept in the built-in FIFO, synchronized to the time stamp value and output.
This IC utilizes Apple Computer’s Fire Wire technology.

Features
