*: On 3x3 package, PL502-35/-38 do not have SEL0 available: Pin 10
is VDD, pin 11 is GND. However, PL502-37/-39 have SEL0 (pin 10),
and pin11 is VDD. See pin assignment table for details.

GREEN/RoHS compliant packages
DESCRIPTION
The PL502-35 (LVPECL with inverted OE), PL502-37
(LVCMOS), PL502-38 (LVPECL), and PL502-39
(LVDS) are high performance and low phase noise
VCXO IC chips. They provide phase noise perfor-
mance as low as –125dBc at 10kHz offset (at
155MHz), by multiplying 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 funda-
mental parallel resonant mode crystals from 12MHz to
25MHz.

Exposure of the device under conditions beyond the limits specified by Maximum R atings 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 dev ice at these or any other
conditions 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 on ly.

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 cr ystal will be at nom-
inal frequency at this load. If the crystal requires more load to be at nominal frequency, the additiona l load must be added externally. This however
may reduce the pull range.
