Output
Positive power supply.
XOUT
Crystal or ceramic resonator output pin. Leave this pin unconnected
(floating) if external clock is used at Pin-3.

XIN/CLKIN
Input
Crystal, ceramic resonator or external clock input pin.
SSCLK4,
REFCLK3,
PD#, OE,
Output or Multi function Programmable SSCLK4 or REFOUT3 clock pin or PD#,
Input
OE, SSON#, or FS control pin. Power Down (PD#-Active Low): If
PD#=0(Low) and Output Enable (OE-Active High).
SSON# or FS
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.

VSS
Power
Output
Power supply ground.
SSCLK2,
REFCLK1
This pin can be programmed as SSCLK2 or REFCLK1 clock pin.
7
8
SSCLK1 or
REFCLK2
Output
This pin can be programmed as SSCLK2 or REFCLK2.
SSCLK4,
REFCLK3,
PD#, OE,
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).
SSON# or FS
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.
