The system designer must select transceivers appropriate to the system requirements to be used with the
TSB14C01A and the link layer selected. The following lists requirements for the transceivers needed.
The transceivers used must be appropriate to the backplane technology used.
The various backplane technologies require different electrical characteristics in their backplanes. For
example BTL uses an operating voltage on the backplane of 2.1 V and a characteristic impedance of 33
while GTL uses an operating voltage of 1.2 V and a characteristic impedance of 50
(see GTL/BTL a Low
Swing Solution for High-Speed Digital Logic TI literature number SCEA003). When a backplane is
designed to use BTL technology, then it would be appropriate to also use that technology for the two lines
dedicated to the 1394 serial bus. The drivers selected also must be able to supply the current required for the
expected backplane loading. For example, BTL operates correctly for a FutureBus configuration backplane
at 50 Mbits/s or for a limited number of nodes in a custom configuration at 100 Mbits/s. See the GTL/BTL a
Low Swing Solution for High-Speed Digital Logic TI literature number SCEA003, Understanding Advanced
Bus-Interface Products TI literature number SCAA029, or the documentation for the transceiver being
considered.
The transceivers used must assert logic states on the backplane in an appropriate manner for the 1394
backplane arbitration.
Arbitration under 1394 backplane rules requires the drivers to assert the bus to indicate a logical 1 state, that
is a logic 1 being driven by the TSB14C01A. Conversely, the drivers should release the bus to indicate a
logic 0 state, a logic 0 being driven by the TSB14C01A. In other words, all drivers must operate in a wired-OR
mode during arbitration.
The transceivers used must be able to monitor the bus and drive the bus at the same time.
