TERMINAL

I/O

DESCRIPTION

NAME

NO.

 

 

 

 

 

 

SCEN

94

O

Speech CODEC enable. A high out from SCEN can enable the speech CODEC.

 

 

 

 

SINT

79

O

Sample interrupt. SINT is active low. In the analog mode, SINT occurs at 40 kHz; in the

 

 

 

digital mode, SINT occurs at 48.6 kHz.

 

 

 

 

SYNCLK

32

O

Synthesizer clock. SYNCLK clocks the serial data stream.

 

 

 

 

SYNDTA

31

O

Synthesizer serial-data. SYNDTA provides the serial bit stream output.

 

 

 

 

SYNLE0

28

O

Synthesizer 0, 1, and 2 latch enables. An active high on SYNLE0, SYNLE1, and

 

 

 

SYNLE2 indicates that the latch is enabled.

SYNLE1

29

O

 

 

 

 

 

SYNLE2

30

O

 

 

 

 

 

SYNOL

27

I

Synthesizer out-of-lock. An active high at SYNOL indicates a synthesizer is not locked.

 

 

 

 

TXEN

23

O

Transmit power enable. An active high output from TXEN can be used to enable various

 

 

 

system transmitter-circuit devices.

 

 

 

 

TXIN

18

O

In-phase differential negative baseband transmit. The negative component of the

 

 

 

differential baseband transmit signal is output from TXIN.

 

 

 

 

TXIP

17

O

In-phase differential positive baseband transmit. The positive component of the

 

 

 

differential baseband transmit signal is output from TXIP.

 

 

 

 

TXONIND

24

I

Transmit on indicator. A signal is applied to TXONIND to indicate that power is applied

 

 

 

to the power amplifier.

 

 

 

 

TXQN

21

O

Quadrature differential negative baseband transmit. The negative component of the

 

 

 

quadrature differential transmit signal is output from TXQN.

 

 

 

 

TXQP

20

O

Quadrature differential positive baseband transmit. The positive component of the

 

 

 

quadrature differential transmit signal is output from TXQP.

 

 

 

 

VCM

15

I

Voltage common mode. VCM establishes the dc operating point for transmit outputs and

 

 

 

can be tied to VHR.

 

 

 

 

VHR

14

O

Voltage half-rail. The voltage level at VHR is approximately 0.5 AVDD. VHR

 

 

 

establishes the dc operating point for receive inputs.

 

 

 

 

VSS

13, 97

Ð

Substrate ground

XTAL

66

I

Crystal input. A crystal connected between XTAL and MCLIN forms an oscillator circuit.
