FEATURES
DESCRIPTION
The PLL502-35 (PECL with inverted OE), PLL502-37
(CMOS), PLL502-38 (PECL), and PLL502-39 (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.

On 3x3 package, PLL502-35/-38 do not have SEL0 available: Pin
10 is VDD, pin 11 is GND. However, PLL502-37/-39 have SEL0
(pin 10), and pin11 is VDD. See pin assignment table for details.
