Description



Features:

3.1 1394 Features
• Integrated 400/200/100-Mbps 2-port/3-port PHY
• Compliant with IEEE Std 1394-1995 and IEEE Std 1394a-2000
• Supports bus manager functions and automatic 1394 self-id verification
• Separate asynchronous acknowledgement (Ack) buffers decrease Ack-tracking burden on external CPU
3.2 DTCP and AES Encryption Support for MPEG-DVB and DSS
(TSB43EA42/43 and TSB43EC42/43 Only)
• DTCP encryption support on 1394 bus
• AES128 encryption support on HSDI path (TSB43EC42/43 only)
• Support for up to two encrypted/decrypted streams at one time
• Full or restricted AKE performed with hardware assist
• Secure method for loading DTCP and AES128 information using Ex-CPU interface
• Localization support compliant with DTCP draft revision 1.51.
3.3 Video Interfaces
• Two configurable high-speed data ports for video data
o One port configurable as parallel or serial
o One port serial only
• Pass-through modes for HSDI0 and HSDI1
• Packet Insertion Two insertion buffers per HSDI for PAT, PMT, SIT, and DIT packets
• PID filtering (32 PID filters per HSDI port)
3.4 External CPU Interfaces
• Motorola 68K-style 16-bit asynchronous interface
• SRAM-like 16-bit asynchronous interface
• PCI interface (33 MHz) compliant to PCI specification version 3.0 (supports PCI slave and master functions)
3.5 DMA
• Higher asynchronous throughput with DMA hardware enhancements (available in PCI mode only)
• Internal DMA controller Asynchronous, asynchronous Stream TX/RX
o General DMA
o Auto-response DMA for SBP2 transactions
3.6 Data Buffers
• Two 4-KByte isochronous buffers for video data
• Two 2-KByte asynchronous/asynchronous stream transmit buffers
• Two 2-KByte asynchronous/asynchronous stream receive buffers
• One 1-KByte self-ID buffer
• Insertion buffers for MPEG-DVB/DSS packet insertion
• Programmable data/space available indicators for buffer flow control
3.7 Hardware Packet Formatting for the Following Standards
• IEC61883-1 (general)
• IEC61883-2 (SD-DVCR)
• IEC61883-4 (MPEG2-TS)
• IEC61883-7 (ITU-R BO.1294 System B) DSS
• Generic 61883 mode
• Asynchronous packets
• Asynchronous streams
• PHY packets (including self-IDs)
• MPEG4 supported under IEC61883-4 (no new requirement for MPEG4 over 1394)
3.8 Additional Features
• JTAG interface to support post-assembly scan of device I/O boundary scan
• Unique "binding" method for protecting sensitive data on the circuit board traces at the Ex-CPU interface
• Unique "EMI-AES Binding" method to prevent protected data from being transmitted in the clear.


Description

The TSB43Ex42/43 is high-performance consumer electronics 1394 link layer and integrated physical layer device designed for digitally interfacing advanced video consumer electronics applications. It upports formatting and transmission of IEC61883 data, including IEC61883-1 (general), IEC61883-2 (SD-DVCR), IEC61883-4 (MPEG2-TS), and IEC61883-7 (ITU-R BO.1294 SystemB-DSS).

TSB43Ex42/43 also supports standard 1394 data types, such as asynchronous, asynchronous streams, and PHY packets.

The TSB43EAxx/ECxx version incorporates DTCP (M6) baseline per the DTLA (5C) specification to support transmit and receive of up to two MPEG2 transport streams with encryption and decryption. The TSB43EAxx/ECxx version also includes hardware acceleration for content key generation.

The TSB43EBxx devices are identical to the TSB43EAxx/ECxx devices, except without implementation of the encryption/decryption features. The TSB43EB42xx/43xx devices allow customers that do not require the encryption/decryption features to incorporate the TSB43Ex42/43 function without becoming DTLA licensees.

The TSB43Ex42/43 features an integrated 2-port/3-port PHY. The PHY operates at 100 Mbps, 200 Mbps, or 400 Mbps. They follow all requirements as stated in IEEE Std 1394-1995 and IEEE Std 1394a-2000.
