Description
Set to “0” (GND) to choose to turn off the oscillator when outputs are disabled (OE). Default (no
connect) is OSC always on.
GND connection for oscillator circuitry.
Control Voltage input. Use this pin to change the output frequency by varying the applied Control
Voltage.
Input from crystal oscillator circuitry.
Output from crystal oscillator circuitry.
Output Enable input (see "OE LOGIC SELECTION TABLE").
Do Not Connect.
External inductor connection. The inductor is recommended to be a high Q small
size 0402 or 0603 SMD component, and must be placed between L4X and adjacent
VDDOSC. Place inductor as close to the IC as possible to minimize parasitic effects
and to maintain inductor Q. This inductor is used with 4X AFMs.
GND connection.
VDD connection for oscillator circuitry. VDDOSC should be separately decoupled from other
VDDs whenever possible.
GND connection for output buffer circuitry.
PECL/LVDS or CMOS output.
Complementary PECL/LVDS output or in phase CMOS.
VDD connection for output buffer circuitry. VDDBUF should be separately decoupled from other
VDDs whenever possible.
VDD connection for analog circuitry. VDDANA should be separately decoupled from other VDDs
whenever possible.
Selector input to choose the OE control logic (see “OE SELECTION TABLE”.
VDD connection for oscillator circuitry. VDDOSC should be separately decoupled from other
VDDs whenever possible.

size 0402 or 0603 SMD component, and must be placed between L2X and adjacent
