DESCRIPTION/ORDERING INFORMATION (CONTINUED)
XIN and XOUT pins can be connected to a crystal or resonator in oscillator applications. The device provides an
additional unbuffered inverter (OSCOUT) and a Schmitt-trigger input inverter for signal conditioning (see
Figure 3
). The control (CTRL) input disables the oscillator circuit to reduce power consumption. The oscillator
circuit is disabled and the XOUT output is set to low level when CTRL is low. To ensure the oscillator circuit
remains disabled during power up or power down, CTRL should be connected to GND through a pulldown
resistor. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

OSCILLATOR DRIVER
FOR CRYSTAL OSCILLATOR OR CERAMIC RESONATOR
SCES469C–AUGUST 2003–REVISED JULY 2005
This device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
NanoStar and NanoFree package technology is a major breakthrough in IC packaging concepts, using the
die as the package.
