1.0 Pin Description (Continued)
45 RXD7 Output Receive Data 7: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
46 RXD6 Output Receive Data 6: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
47 RXD5 Output Receive Data 5: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
48 CORE_VDD Power Core VDD: (Digital) Connect to 1.8V.
49 VSS Ground Ground: Connect to common ground plane.
50 RXD4 Output Receive Data 4: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
51 RXD3/RX3 Output Receive Data 3: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
52 RXD2/RX2 Output Receive Data 2: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
53 IO_VDD Power I/O VDD: (Digital) Connect to 2.5V or 3.3V. The
VDD_SEL pin must be tied accordingly.
54 VSS Ground Ground: Connect to common ground plane.
55 RXD1/RX1 Output Receive Data 1: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
56 RXD0/RX0 Output Receive Data 0: Connect to MAC chip through
a single 50 Ω impedance trace. This output is ca-
pable of driving 35 pf load and is not intended to
drive connectors, cables, backplanes or multiple
traces. This applies if the part is in 100 Mbps
mode or 1000 Mbps mode.
