PIN NAME PIN NUMBER PIN I/O TYPE
DESCRIPTION
GRESET
L15
I
Global Reset for MAC, Active LOW
TCLKIN(CS)
L4
I/O, 50K Pull CS used for Chip Select Output for Serial Devices which have a 4 wire interface like the
Down
AST45DB011 and also serial data on two wire devices like the 24C08.
ANTSEL
N15
O
The antenna select signal changes state as the receiver switches from antenna to antenna during
the acquisition process in the antenna diversity mode. This is a complement for ANTSEL (pin 40) for
differential drive of antenna switches.
ANTSEL
N16
O
The antenna select signal changes state as the receiver switches from antenna to antenna during
the acquisition process in the antenna diversity mode. This is a complement for ANTSEL (pin 39) for
differential drive of antenna switches.
