I/O Description
71 I/O GPIO8. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
72 I/O GPIO9. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
87 I/O GPIO10. Can be programmed as general-purpose input,
general-purpose output, or specific function. Power-up default
is input.
29 I/O Twisted Pair A Differential Signal Terminals. For an unused
36 port, TPAN and TPAP signals can be left open.

31 Twisted Pair Bias Output. These signals provide the 1.86V
38 I/O nominal bias voltage needed for proper operation of the
44 twisted pair driver and receivers for signaling an ìactive
connectionî to a remote node.
For an unused port, TPBIAS can be left unconnected.
46 Current Setting Resistors. These pins are connected to
47 external resistors to set the internal operating currents and
cable driver output currents. A resistance of 6.34kΩ ± 1% is
-
required to meet the IEEE 1394-1995 output voltage limits.
49 PLL Filter Terminals. These terminals are connected to an
50 I/O external capacitor to form a lag-lead filter required for stable
operation of the internal frequency-multiplier PLL, which is
using the crystal oscillator. A 0.1 µF± 10% capacitor is the
only external component required to complete this filter.
52 Crystal Oscillator Inputs. These terminals connect to a 24.576
53 - MHz parallel resonant fundamental mode crystal. The
optimum values for the external shunt capacitors are
dependent on the crystal used.
21 I Cable Power Status. Input to iceLynx-Micro used to detect if
cable power is present. This pin should be connected to the
cable power through 390 kΩ resistor.
19 I
61 O Link On output. This signal is asserted whenever LPS is low
and a Link On packet is received from the 1394 bus.
173 I 60958 Data Input.
