Pin Number

Pin Name

Pin Function

12, 9

IN, /IN

Differential Input: Internal 50ý termination resistors to V

differential input. See “Input Interface Applications” section.

1, 2, 3, 4

Q0, /Q0

Differential Buffered LVDS Outputs: Divided by 1, 2, 4, 8 or 16. See “Truth Table.”

Q1, /Q1

Unused output pairs must be terminated with 100ý across the different pair.

16, 15, 5

S0, S1, S2

Select Pins: See “Truth Table.” LVTTL/CMOS logic levels. Internal 25ký pull-up resistor.

6

NC

No Connect.

8

/RESET,

LVTTL/CMOS Logic Levels: Internal 25ký pull-up resistor. Logic HIGH if left unconnected.

/DISABLE

Apply LOW to reset the divider (divided by 2, 4, 8 or 16 mode). Also acts as a disable/enable

function. The reset and disable function occurs on the next high-to-low clock input transition.

10

VREF-AC

Reference Voltage: Equal to V

Decouple the VREF–AC pin with a 0.01µF capacitor. See “Input Interface Applications” section.

11

VT

Termination Center-Tap: For CML or LVDS inputs, leave this pin floating. Otherwise, See

Figures 4a to 4f “Input Interface Applications” section.

7, 14

VCC

Positive Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitor.

13

GND, Exposed

Ground. Exposed pad must be connected to the same potential as the GND pin.
