CRYSTAL OSCILLATOR DRIVER
SCES581B – JULY 2004 – REVISED DECEMBER 2006
X1 and X2 can be connected to a crystal or resonator in oscillator applications. The device provides an
additional buffered inverter (Y) for signal conditioning (see Figure 3 ). The additional buffered inverter improves
the signal quality of the crystal oscillator output by making it rail to rail.
NanoStar™ and NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the
die as the package.
This device is fully specified for partial-power-down applications using I
off
(Y output only). The I
off
circuitry
disables the outputs, preventing damaging current backflow through the device when it is powered down.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
(3) The value of V

(4) The package thermal impedance is calculated in accordance with JESD 51-7.
