DESCRIPTION

GRESET

L15

I

Global Reset for MAC, Active LOW

TCLKIN(CS)

L4

I/O, 50K Pull

Down

CS used for Chip Select Output for Serial Devices which have a 4 wire interface like the

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.
