DESCRIPTION
CMOS Local Clock : A 25Mhz clock, +/- 100 PPM, 40%-60% duty
cycle. The signal not supports 5 Volts tolerance.
Crystal Oscillator Input : A 25Mhz crystal, +/- 25 PPM can be
connected across XTALIN and XTALOUT.
Crystal Oscillator Output : A 25Mhz crystal, +/- 25 PPM can be
connected across XTALIN and XTALOUT. If a single-ended external
clock (LCLK) is connected to XTALIN, the crystal output pin should
be left floating.
Clock Output : This clock is source from LCLK/XTALIN.
Reset :
Reset is active high then place AX88796 into reset mode immediately.
During the falling edge the AX88796 loads the power on setting data.

LED Indicator Option : Selection of LED display mode.
I_OP = 0: I_LK/ACT, I_SPEED and I_FULL/COL LED display
mode.
I_OP = 1: I_LINK, I_SPEED and I_ACT LED display mode. (default)
Test Pins
:
Active high
These pins are just for test mode setting purpose only. Must be pull
down or keep no connection when normal operation.
For test only. Must be pulled down at normal operation.
For test only. Must be pulled down or keep no connection when normal
operation.
This sets the common mode voltage for 10Base-T and 100Base-TX
modes. It should be connected to the center tap of the transmit side of
the transformer
No Connection : for manufacturing test only.
