QB1, /QB1
Differential Buffered Output Clocks: The differential output is a divided-down version of the
input frequency and has a matched output delay with Bank A. Divided by 2, 4, 8, or 16. See
“Truth Table.” Unused output pairs may be left floating.

QA, /QA
Differential Buffered Undivided Output Clock.

VCC
Positive Power Supply: Bypass with 0.1F and 0.01F low ESR capacitors.
8
/RESET
Output Reset: Internal 25K
Ω pull-up. Logic LOW will reset the divider select. See “Truth Table.”
Input threshold is VCC/2.
12, 9
IN, /IN
Differential Input: Internal 50
Ω termination resistors to VT input. See “Input Interface
Applications” section.
10
VREF-AC
Reference Voltage: Equal to VCC–1.4V (approx.), and used for AC-coupled applications. For
DC-coupled applications, VREF-AC is normally left floating. Maximum sink/source current is
0.5mA. See “Input Interface Applications” section.
11
VT
Input Termination Center-Tap: Each side of differential input pair terminates to this pin. The VT
pin provides a center tap to a termination network for maximum interface flexibility. For CML
and LVDS inputs, leave this pin floating. See “Input Interface Application” section.
13
GND
Ground.
15, 16
S1, S0
Select Pins: See “Truth Table.” LVTTL/CMOS logic levels. Internal 25KΩ pull-up resistor. Logic
HIGH if left unconnected (divided by 16 mode). S0 = LSB. Input threshold is VCC/2.
