DESCRIPTION
The ABV0235 (PECL with inverted OE), ABV0237
(CMOS), ABV0238 (PECL), and ABV0239 (LVDS)
are high performance and low phase noise VCXO IC
chips. They provide phase noise performance as low
as –125dBc at 10kHz offset (at 155MHz), by multi-
plying the input crystal frequency up to 32x. The
wide pull range (+/- 200 ppm) and very low jitter
make them ideal for a wide range of applications,
including SONET/SDH and FEC. They accept fun-
damental parallel resonant mode crystals from 12 to
25MHz.

10 is VDD, pin 11 is GND. However, ABV0237/-39 have SEL0 (pin
10), and pin11 is VDD. See pin assignment table for details.

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other con-
ditions above the operational limits noted in this specification is not implied.
* Note: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.

Note: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. It is assumed that the crystal will be at nomi-
nal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This however may
reduce the pull range.
