Overview

The SBPH400-3 provides the analog transceiver functions needed to implement a 3 port node in an IEEE 1394-1995 cable network. There are 2 differential line transceivers in each cable port. The following main functions are included in the chip:

? Detection of connection status using line condition detection circuitry.

? Node initialization and bus arbitration.

? Reception and Transmission of Data Strobe Bit Level encoded packets

? Interface to higher level protocol devices (Link layer).

? Production test through JTAG
