Test 1

TEST1

Test 1 pin.

This signal is used for test purposes and

must always be pulled-up to 3.3V via a 10

 resistor.

Pull to 3.3V

through a

10 k



resistor

Test 2

TEST2

Test 2 pin.

This signal is used for test purposes and

must always be pulled-up to 3.3V or GND

via a 10 k

 resistor.

Pull to 3.3V

or GND

through a

10 k



resistor

Test 3

TEST3

Test 3 pin.

This signal is used for test purposes and

must always be pulled-up to 3.3V or GND

via a 10 k

 resistor.

Pull to 3.3V

or GND

through a

10 k



resistor

Reset Input

RESET_N

This active low signal is used by the system

to reset the device.

Mandatory

Note 3-8

Bias Resistor

RBIAS

I-R

A 12.0 k

 1.0% resistor is attached from

ground to this pin to set the transceiver’s

internal bias settings. Place the resistor as

close the device as possible with a dedi-

cated, low impedance connection to the

ground plane.

Mandatory

Note 3-8

Test

TESTEN

I/O12

Test pin.

This signal is used for test purposes and

must always be connected to ground.

Connect to

GND

Analog Test

ATEST

Analog test pin.

This signal is used for test purposes and

must always be left unconnected.

Float

External 25 MHz

Crystal Input

XTALI

ICLK

External 25 MHz crystal input

Mandatory

Note 3-8

External 25 MHz

Reference Clock

Input

CLK_IN

ICLK

External reference clock input.

The device may alternatively be driven by a

single-ended clock oscillator. When this

method is used, XTALO should be left

unconnected.

Mandatory

Note 3-8

External 25 MHz

Crystal Output

XTALO

OCLK

External 25 MHz crystal output

Float

(only if sin-

gle-ended

clock is

connected

to CLK_IN)
