NOTES
1. DNC = DO NOT CONNECT.
2. IT IS RECOMMENDED THAT THE EXPOSED PAD BE SOLDERED
TO THE GROUND PLANE FOR THE LFCSP PACKAGE. THERE IS
AN INCREASED RELIABILITY OF THE SOLDER JOINTS, AND
THE MAXIMUM THERMAL CAPABILITY OF THE PACKAGE IS
ACHIEVED WITH THE EXPOSED PAD SOLDERED TO THE
CUSTOMER BOARD.

Description
Out-of-Range Indicator.
Data Format and Clock Duty Cycle Stabilizer (DCS) Mode Selection.
Reference Mode Selection.
Voltage Reference Input/Output.
Differential Reference (Negative).
Differential Reference (Positive).
Analog Power Supply.
Analog Ground.
Analog Input Pin (+).
Analog Input Pin (−).
Clock Input Pin.
Power-Down Function Selection (Active High).
Do not connect, recommend floating this pin.
Data Output Bits.
Digital Output Ground.
Digital Output Driver Supply. Must be decoupled to DRGND with a
minimum 0.1 μF capacitor. Recommended decoupling is 0.1 μF in parallel with 10 μF.
Exposed Pad. It is recommended that the exposed pad be soldered to the ground plane
for the LFCSP package. There is an increased reliability of the solder joints, and the
maximum thermal capability of the package is achieved with the exposed pad soldered
to the customer board.
