- Compliant with IEEE 1394-1995 and IEEE 1394a-2000 standards
- MPEG2 time stamp-based release, as described in IEC 61883-4
- High-speed data interface (HSDI):
- Byte-wide or serial mode
- Two independent HSDI ports
- Bidirectional
- Several control modes for a variety of applications
- Connects seamlessly to common MPEG2 decoder chipsets
- 16-bit microprocessor interface supports Motorola 68000/68020-style bus

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.
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.
