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 鈥?25dBc 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.

On 3x3 package, ABV0235/-38 do not have SEL0 available: Pin
10 is VDD, pin 11 is GND. However, ABV0237/-39 have SEL0 (pin
10), and pin11 is VDD. See pin assignment table for details.
