3-port physical layer interface
Preliminary specification
PDI1394P11A
associated link controller. The received data is also transmitted out
the other active cable ports.
The cable status, bus initialization and arbitration states are
monitored through the cable interface using differential comparators.
The outputs of these comparators are used by internal logic to
determine cable and arbitration status. The TPA channel monitors
the incoming cable common-mode voltage value during arbitration to
determine the speed of the next packet transmission. The TPB
channel monitors the incoming cable common-mode voltage for the
presence of the remotely supplied twisted-pair bias voltage,
indicating the cable connection status.
The PDI1394P11A provides a nominal 1.85 V for driver load
termination. This bias voltage, when seen through a cable by a
remote receiver, is used to sense the presence of an active
connection. The value of this bias voltage has been chosen to allow
inter-operability between transceiver chips operating from either 5 V
nominal supplies, or 3.3 V nominal supplies. This bias voltage
source should be stabilized by using an external filter capacitor. When
not powered, the PDI1394P11A prevents the bias voltage from
erroneously powering up the part as is seen in some other Phys.
