Pin Number
Pin Name
Pin Function
1, 2, 3, 4
QB0, /QB0
Differential Buffered Output Clocks: Divide by 2, 4, 8, 16.
QB1, /QB1
LVDS compatible.
5, 6
QA, /QA
Differential Buffered Undivided Output Clock: LVDS compatible.
7, 14
VCC
Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors.
8
/RESET,
TTL/CMOS Compatible Output Reset and Disable: Internal 25k pull-up. Input threshold
/DISABLE
is VCC/2. Logic LOW will reset the divider select, and align Bank A and Bank B edges. In
addition, when LOW, Banks A and B will be disabled.
12, 9
IN, /IN
Differential Input: Internal 50 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.
Maximum sink/source current is 0.5mA. See
“Input Interface Applications” section.
11
VT
Termination Center-Tap: For CML and LVDS inputs, leave this pin floating. Otherwise,
see
“Input Interface Applications” section.
13
GND
Ground: Exposed pad is internally connected to GND and must be connected to a ground
plane for proper thermal operation.
16, 15
S0, S1
Select Pins: LVTTL/CMOS logic levels. Internal 25k pull-up resistor. Logic HIGH if left
unconnected (divided by 16 mode). S0 = LSB. Input threshold is VCC/2.
