De scr ip tio n
AC Test Point. Positive and Negative.
These pins are also used to bring out a differential TX_TCLK. Connect
these pins with a 50 ohm termination resistor to VSS for IEEE testing and
debug purposes. If debug and IEEE testing are not of importance, these
pins can be left floating.
Test Point.
De scr ip tio n
Constant voltage reference. External 4.99 kohm 1% resistor connection to
VSS required for each pin.
1.8V Regulator Control. This signal ties to the base of the BJT. If the 1.8V
regulator is not used it can be left floating.
1.2V Regulator Disable. Tie to VDDO to disable, tie to VSS to enable.
