Receive Clock/ Receive Byte Clock 1: Con-
nect to MAC chip through a single 50
ance trace. This output is capable of driving 35
pf load and is not intended to drive connectors,
cables, backplanes or multiple traces. This ap-
plies if the part is in 100 Mbps mode or 1000
Mbps mode.
I/O VDD: (Digital) Connect to 2.5V or 3.3V. The
VDD_SEL pin must be tied accordingly.
Transmit Clock: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF.
Transmit Error: Connect to MAC chip through a
single 50
typical input capacitance of 6 pF.
Transmit Enable: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF.
Core VDD: (Digital) Connect to 1.8V.
Transmit Data 7: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF.
Transmit Data 6: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
Transmit Data 5: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
Transmit Data 4: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
I/O VDD: (Digital) Connect to 2.5V or 3.3V. The
VDD_SEL pin must be tied accordingly.
Transmit Data 3: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
Transmit Data 2: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
Core VDD: (Digital) Connect to 1.8V.
Transmit Data 1: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
Transmit Data 0: Connect to MAC chip through
a single 50
typical input capacitance of 6 pF
I/O VDD: (Digital) Connect to 2.5V or 3.3V. The
