Recommendations
(Default)
• Connect to EEPROM Shift Clock input (SK)
• Connect through a 4.7KΩ ±5% resistor to Ground.
O
Note:
• Can be left as NC when none of GBE ports is connected to an interfacing
device
• Connect to EP80579 PME# Input
OD O
• Pull-up to EP80579 3.3V Standby (VCCPSUS) supply through a 10 KΩ ±5%
resistor
• Connect to Platform GBE_AUX_PWR_GOOD
I
Note:
• Connect to SYS_PWR_OK if standby voltages are not generated.
• Connect appropriately to the
three mezzanine card
connectors.
I/O
• Each connector supports two
TDM (HSS) ports to be
compatible with previous voice
mezzanine cards.
(See
Section 22.3.3
• Address Latch Enable
O
• Used for multiplexed address/
data bus accesses
Comments
Note:
• If an interface is not used or
connected to a device, each
interface signal should be pulled
high through 10 KΩ resistors.
for more details)
• Used in Intel, Motorola, and HSS
multiplexed modes of operation
Note:
• Can be left as no connect (NC)
when the interface is not connected
to an interfacing device or not used
