CAP1

I

Connect a ceramic capacitor and a resistor in series between this pin and CAP2. Refer to page 4.

5

GND

P

Connect to ground.

6

CAP2

I

Connect a ceramic capacitor and a resistor in series between this pin and CAP1. Refer to page 4.

7

GND

P

Connect to ground.

8

FS0

I

Frequency Select 0. Determines CLK outputs per table above.

11

CLK2

O

Clock 2 determined by status of FS3:0 per table above.

12

CLK3

O

Clock 3 determined by status of FS3:0 per table above.

13

FS1

I

Frequency Select 1. Determines CLK outputs per table above.

14

FS2

I

Frequency Select 2. Determines CLK outputs per table above.

15

N/C

-

No Connect. Nothing is connected to this pin.

16

FS3

I

Frequency Select 3. Determines CLK outputs per table above.
