DESCRIPTION

NAME

NO.

I/O

DESCRIPTION

ALTIN

26

I

Serial input in the

event monitor mode

AURXCP

3

I

Receiver-path/GP amplifier noninverting input. It needs to be connected to AVSS if not used.

AURXM

2

I

Receiver-path amplifier A1 inverting input, or inverting input to auxiliary analog input. It needs to be connected

to AVSS if not used. It can also be used for general-purpose amplification.

AURXFP

1

I

Receiver-path amplifier A1 feedback, or noninverting input to auxiliary analog input. It needs to be connected

to AVSS if not used. It can also be used for general-purpose amplification.

AVDD1

AVDD2

45

34

I

Analog ADC power supply (3 V to 5.5 V)

AVSS

33, 40, 42,

46

I

Analog ground

DCSI

25

I

Direct configuration serial input for directly programming of internal control registers

DIN

17

I

Data input. DIN receives the DAC input data and register data from the external digital signal processor (DSP),

and is synchronized to SCLK and FS. Data is latched at the falling edge of SCLK when FS is low. DIN is at high

impedance when FS is not activated.
