DESCRIPTION
GDLNK
53
Power Pins
O/TTL
GoodLink:
This output asserts low if the PENTIC+ is in TPI mode,
link checking is enabled, and the link integrity is good or
if link checking is disabled; otherwise, is not asserted.
This output can also be controlled by power down state
machine; refer to the description of the COR and CFA
registers for more details.
AVCC
61
Analog Power Supply Pins:
These pins supply +5V to the PENTIC+'s analog
circuitry for the network interface. Analog layout rules
and decoupling methods must be applied between this
pin and AGND.
AGND
62
Analog Ground Pins:
These pins are the ground to the analog circuitry.
VCC
3, 16, 45, 83
Digital Power Supply Pins:
These pins supply +5V to the PENTIC+'s digital
circuitry.
GND
5, 14, 43,
56, 85
Digital Ground Pins:
These pins are the ground to the digital circuitry.
Note: I: input pin; O: output pin; IO: bidirectional input/output pin; TTL: TTL level buffer stage; ODH: open drain buffer stage;
MOS: MOS level buffer stage; 3SH: Tri-state buffer stage; DIF: differential buffer stage, XTAL: crystal.
