Name/Description
Global Reference Clock. Differential reference clock input pair. This clock
is used as the reference clock by on-chip PLLs to generate the clocks
required for the system logic. The frequency of the differential reference
clock is determined by the GCLKFSEL signal.

Name/Description
Master SMBus Address. These pins determine the SMBus address of the
serial EEPROM from which configuration information is loaded.
Master SMBus Clock. This bidirectional signal is used to synchronize
transfers on the master SMBus.
Master SMBus Data. This bidirectional signal is used for data on the mas-
ter SMBus.
Slave SMBus Address. These pins determine the SMBus address to
which the slave SMBus interface responds.
Slave SMBus Clock. This bidirectional signal is used to synchronize trans-
fers on the slave SMBus.
Slave SMBus Data. This bidirectional signal is used for data on the slave
SMBus.
