BGRES
O
Band gap resistor
It is connected to GND through a 6.19k (1%) resistor in
application circuit.
18
FXSD
I
100Base-FX signal detect
Fiber signal detect. It is an input signal from fiber MAU.
Fiber signal detect is active if the voltage on FXSD is
higher than the threshold voltage, which is 1.35v
±5%
when VCC is equal to 2.5v.
13, 14
FXRDP, FXRDM
I
Fiber receiver data pair
Common-mode voltage of FXRDP and FXRDM are
suggested to near 0.5x AVCC.
When voltage peak-to-peak>0.1V,FXRX could be
workable.
16, 17
FXTDP, FXTDM
O
Fiber transmitter data pair
FXTX with the external 100Ω resistor.
Common-mode voltage of FXTDP and FXTDM are
suggested to near 0.5x AVCC.
Swing of Voltage ≧ 0.8V.
