TSB42AB4PDT

The TSB42AB4PDT is an IEEE 1394 link layer controller manufactured by Texas Instruments, designed for consumer electronics applications. This device interfaces directly with industry-standard physical layer devices and is compliant with IEEE 1394-1995 and IEEE 1394a-2000 standards.

Key electrical specifications include a single 3.3V supply voltage. The controller features a 16-bit microprocessor interface supporting Motorola 68000/68020-style buses and a large 8K-byte FIFO that can be configured for various data types, including DVB MPEG2 transport streams and DV program streams. It also supports external processor DMA and provides programmable data/space available indications for flow control.

Packaged in a 128-TQFP (14x14) form factor, the TSB42AB4PDT operates within a temperature range of 0°C to 70°C. It offers two independent High-Speed Data Interface (HSDI) ports, supporting both byte-wide and serial modes, and is bidirectional. The device includes embedded support for DTCP content protection, a random number generator, and SHA-1 secure hash algorithm in hardware.

This controller is suitable for applications requiring high-speed data transfer compliant with IEEE 1394 standards, such as digital video recorders, set-top boxes, and other consumer multimedia devices. Its robust feature set and compatibility with standard physical layer devices make it a versatile choice for interface designs.
