DESCRIPTION
Consumer Electronics Link (ceLynx) is a high-performance 1394 link layer device designed specifically to
support advanced consumer electronics applications, particularly those applications which require the
transmission of Moving Picture Expert Group 2 (MPEG2) transport streams and encryption/decryption of those
streams across a 1394 network. The device supports both digital video broadcasting (DVB) and DirecTV™ type
MPEG2 streams using the digital transmission content protection method (DTCP) method of encryption, as well
as digital video (DV) encoded streams. The ceLynx supports both the IEC 61883 standard for DVB and DV
streams over 1394 and the 1394 Trade Association standard for DirecTV over 1394.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

The ceLynx is also versatile enough to handle asynchronous data and asynchronous streams. A key feature of
the ceLynx is its ability to handle multiple data type streams simultaneously; the user may transport DVB,
DirecTV, DV data streams, and asynchronous data simultaneously. The ceLynx can also support multiple
streams of the same data type simultaneously, (for example, transmit or receive two DVB transport streams or
two DV streams).
The ceLynx is full duplex, allowing simultaneous playback and recording of audio/video data. Full duplex support
also includes the capability of using the DTCP method, simultaneously using the two embedded M6 cipher
modules. The large internal 8-Kbyte FIFO is very flexible, allowing the user to partition it into eight independent
first in first out (FIFOs) and allowing the user to determine the exact configuration of each of these FIFOs to fit
the application. Advanced features have been added to support program ID (PID) filtering and packet insertions.
The ceLynx is also designed to interface seamlessly with popular MPEG2 decoder chipsets. This decreases the
design-in effort of customers when using these popular chipsets.
