Function Pins

PF[31:4]

I/O12

Programmable function pins.

Refer to Section 3.3, Configuration Straps and Program-

mable Functions for details.

Reset Input

RESET_N

This active low signal is used by the system to reset the

device.

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.

Test 1

TEST1

Test 1 pin.

This signal is used for test purposes and must always

be pulled-up to 3.3V via a 4.7 k

 resistor.

Test 2

TEST2

Test 2 pin.

This signal is used for test purposes and must always

be pulled-down to ground via a 4.7 k

 resistor.

Test 3

TEST3

Test 3 pin.

This signal is used for test purposes and must always

be pulled-down to ground via a 4.7 k

 resistor.

Test

TESTEN

I/O12

Test pin.

This signal is used for test purposes and must always

be connected to ground.

Analog Test

ATEST

Analog test pin.

This signal is used for test purposes and must either be

left unconnected or tied to ground.

External 25 MHz

Crystal Input

XTALI

ICLK

External 25 MHz crystal input

External 25 MHz

Reference Clock

Input

CLKIN

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.

External 25 MHz

Crystal Output

XTALO

OCLK

External 25 MHz crystal output
