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
