Link Fault Pass Through
IP113 supports link fault pass through in TX/FX converter
application. This function is enabled if pin 57(LFP) is tied
to VCC. When IP113 works at this mode, port 0 is a TP
port with auto-negotiation capability and port 1 is a fiber
port. Link status on one port is propagated to the other
port to notice the remote nodes.
If TP port is unplugged, IP113 stops transmission on fiber
port. This causes the remote fiber node link fails. LED
shows link failure on both TP port and fiber port. If fiber
link fails, IP113 restarts auto-negotiation on TP port but
always stays in the link failure state. This causes the
remote TP node link fails. LED shows link failure on both
TP port and fiber port.
LED and Initial Value Setting
IP113 supports two ways to modify its initial values of
operation parameters to fit different applications. It read
the initial value via pins or EPROM interface.
Initial Value Set Via Pins
To set the parameter via pins, connect them to vcc or
ground through resistors. IP113 reads initial value via
pins during the period of reset. An initial value is set to
1’b1 (1’b0) by connecting a pin to vcc (gnd) through a
10k
(1k
) resistor as shown on the following figure.
The function begins after the internal PLL clock active. To
make sure the proper operation of PLL, the duration of
reset must be no less than 1 ms. When there is no
setting resistor, IP113 uses the default value.
IP113 reads initial setting via pins during the period of
reset. At reset, these pins are input signals and IP113
reads the initial value. After reset, LED pins become
output signals and show LED functions at normal mode.
The application circuit is shown below.
