产品描述

The TSB43Ex42/43 is high-performance consumer electronics IEEE 1394 link layer and integrated physical layer devices designed for digitally interfacing advanced video consumer electronics applications. It supports 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). The TSB43Ex42/43 also supports standard IEEE 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 series are identical to the TSB43EAxx/ECxx series without implementation of the encryption/decryption features. The TSB43EB42/43 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 the IEEE 1394-1995 and IEEE 1394a-2000 standards.

Designing with this device may require extensive support. Before incorporating this device into a design, customers should contact TI or an Authorized TI Distributor.
