EEPROM Option
The user may choose to configure theVSC8211 via an EEPROM load. In order to
program the EEPROM properly, pull-up or pull-down resistors must be configured for
either R6 – R8 or R24 – R26. Please refer to Section 19 of the datasheet regarding to
EEPROM programming requirement.
2.1.11
CMODE Pins (Pin-Strap mode)
On the upper right of the board, there is an option to change the CMODE pin pull-up or
pull-down resistors, R9 - R17 and R27-R34. Please refer to Section 18 of the datasheet
for the detail on how to program the desired operating condition parameters through
the CMODE configuration bits and how to choose the value of each CMODE pull-up or
pull-down resistor.
2.1.12
LED Interface
LED1 to LED5 are available on the lower left of the board. Please refer to Section 14 of
the datasheet for details regarding how to configure the LEDs.
2.1.13
CLOCKOUT SMA
The user should observe a 125MHz output clock through this SMA if the internal PHY
PLL is operating properly.
2.2
Software Requirements
The VSC8211 GUI can be loaded on to any PC or laptop that complies with the
following requirements:
1.
The PC must run a recent version of MS-Windows. According to the Microsoft
