(ceLynx) IEEE 1394-a Consumer Electronics Link Layer Controller
FEATURES
• DTCP content protection (TSB42AA4 only). A
separate document explains the DTCP
hardware errata for TSB42AA4. It is available
upon request to DTLA licensees only.
• Interfaces directly to industry standard 400-,
200-, and 100-Mbps physical layer devices,
including Texas Instruments TSB41LV0X and
TSB41AXX family of physical layer devices
• 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
• Large 8K-byte FIFO can be configured up to
eight independent Tx or Rx FIFOs
• 8K-byte FIFO supports the following data
types:
– DVB MPEG2 transport streams (IEC
61883-4)
– DirecTV™ transport streams
– DV program streams (IEC 61883-2)
– Asynchronous streams
– Support for external processor DMA
• Programmable data-/space-available
indications for flow control; almost full and
almost empty indicators
• Supports bus manager functions and
automatic 1394 self-ID verification
• Interrupt driven to minimize host polling
• Single 3.3-V supply
• Separate async acknowledge buffer
decreases the ack-tracking burden on host
• JTAG interface to support post-assembly
scan of device I/O
• Bus holder isolation
• Embedded support for DTCP content
protection:
– Two M6 baseline ciphers (one per HSDI
port)
– Random number generator in hardware
– SHA-1 secure hash algorithm in hardware
– Authentication key cipher in hardware
• Optional auto-configuration for MPEG2/DV
transmit and receive functions
• PID filtering and packet insertion for MPEG2
transport stream
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.
