Pin Description

1

VDD

Power

Positive power supply.

2

XOUT

Output

Crystal or ceramic resonator output pin. Leave this pin unconnected

(floating) if external clock is used at Pin-3.

3

XIN/CLKIN

Input

Crystal, ceramic resonator or external clock input pin.

4

SSCLK4,

REFCLK3,

PD#, OE,

SSON# or FS

Output or

Input

Multi function Programmable SSCLK4 or REFOUT3 clock pin or PD#,

OE, SSON#, or FS control pin. Power Down (PD#-Active Low): If

PD#=0(Low) and Output Enable (OE-Active High).

If PD# or OE is programmed, the pin is weakly pulled high to VDD.

If SSON# or FS is programmed, the pin is weakly pulled low to VSS.

5

VSS

Power

Power supply ground.

6

SSCLK2,

REFCLK1

Output

This pin can be programmed as SSCLK2 or REFCLK1 clock pin.

7

SSCLK1 or

REFCLK2

Output

This pin can be programmed as SSCLK2 or REFCLK2.

8

SSCLK4,

REFCLK3,

PD#, OE,

SSON# or FS

Input or

Output

Multi function Programmable SSCLK4 or REFOUT3 clock pin or PD#,

OE, SSON# or FS control pin. Power Down (PD#-Active Low): If

PD#=0(Low) and Output Enable (OE-Active High).

If PD# or OE is programmed, the pin is weakly pulled high to VDD.

If SSON# or FS is programmed, the pin is weakly pulled low to VSS.

Notes:

1. Pull-down/up resisters can be programmed to VDD or VSS as required. The above programming values are

default values.

2. Refer to DC electrical specifications tables for pull-down/up resistor values.
