Name Pin# Type Product
Description
OSCOFFSEL 1
I
2X & 4X
Set to “0” (GND) to choose to turn off the oscillator when outputs are
disabled (OE). Default (no connect) is OSC always on.
GNDOSC
2 P 2X & 4X GND connection for oscillator circuitry.
VCON
3
I
2X & 4X
Control Voltage input. Use this pin to change the output frequency by
varying the applied Control Voltage.
XIN
4 I 2X & 4X Input from crystal oscillator circuitry.
XOUT
5 O 2X & 4X Output from crystal oscillator circuitry.
OE
6 I 2X & 4X Output Enable input (see "OE LOGIC SELECTION TABLE").
DNC
2X Do Not Connect.
L4X
7I
4X
External inductor connection. See INDUCTOR VALUE OPTIMIZATION on
page 5. This inductor is used with 4X AFMs.
GNDANA
VDDOSC*
8P
2X GND connection.
4X V_DD connection for oscillator circuitry.
GNDBUF
9 P 2X & 4X GND connection for output buffer circui try.
Q
10 O 2X & 4X PECL/LVDS or CMOS output.
QBAR
11 O 2X & 4X Complementary PECL/LVDS output or in phase CMOS.
VDDBUF* 12 P 2X & 4X V_DD connection for output buffer circuitry.
VDDANA*
OESEL
13 P 2X & 4X V_DD connection for analog circuitry.
14
I
2X & 4X
Selector input to choose the OE control logic (see “OE SELECTION
TABLE”). Internal pull-down.
VDDOSC* 15 P 2X & 4X V_DD connection for oscillator circuitry.
L2X
16
I
2X & 4X
External inductor connection. See INDUCTOR VALUE OPTIMIZATION on
page 5.
* All VDD pins should be separately decoupled whenever possible.
