I/O
Twisted-pair bias output. This provides the 1.86 V nominal bias voltage needed for proper
operation of the twisted-pair cable drivers and receivers, and for signaling to the remote
nodes that there is an active cable connection. These terminals must be decoupled with a

Crystal oscillator inputs. These terminals connect to a 24.576 MHz parallel resonant
fundamental mode crystal. The optimum values for the external shunt capacitors are
dependent on the specifications of the crystal used. Can also be driven by an external
clock generator (leave XO unconnected in this case and start supplying the external clock
before resetting the PDI1394P25). For more information, refer to Section 17.5
