No connect.
2, 20
VDDO
Power
Output supply pins.
3, 4
Q0, nQ0
Output
Differential output pair. LVHSTL interface levels.
5
MR
Input
Pulldown
Active HIGH Master Reset. When logic HIGH, the internal dividers are reset
causing the true outputs Qx to go low and the inverted outputs nQx to go high.
When logic LOW, the internal dividers and the outputs are enabled.
LVCMOS/LVTTL interface levels.
6
nPLL_SEL
Input
Pulldown
PLL select control. When LOW, the selected reference clock is
frequency-multiplied by the PLL. When HIGH, the PLL is bypassed and the
selected reference clock is routed directly to the output dividers.
LVCMOS/LVTTL interface levels.
8VDDA
Power
Analog supply pin.

F_SEL0,
F_SEL1
Input
Pulldown
Frequency select pins. LVCMOS/LVTTL interface levels.

Power
Core supply pins.
12, 13
XTAL_OUT,
XTAL_IN
Input
Parallel resonant crystal interface. XTAL_OUT is the output,
XTAL_IN is the input.
14
REF_CLK
Input
Pulldown
Single-ended reference clock input. LVCMOS/LVTTL interface levels.
15
nXTAL_SEL
Input
Pulldown
Selects between crystal or REF_CLK inputs as the PLL Reference source.
Selects XTAL inputs when LOW. Selects REF_CLK when HIGH.
LVCMOS/LVTTL interface levels.
17
GND
Power
Power supply ground.
18, 19
nQ1, Q1
Output
Differential output pair. LVHSTL interface levels.
