DESCRIPTION
The PL602-35 (LVPECL with inverted OE), PL602-37
(LVCMOS), PL602-38 (LVPECL), and PL602-39
(LVDS) are high performance and low phase noise XO
IC chips. They provide phase noise performance as
low as 127dBc at 10kHz offset (at 155MHz), by multi-
plying the input crystal frequency up to 32x. The very
low jitter makes them ideal for a wide range of applica-
tions, including SONET/SDH and FEC. They accept
fundamental parallel resonant mode crystals from
12MHz to 25MHz.

*: On QFN package, PL602-35/-38 do not have SEL0 available: Pin 10
is VDD, pin 11 is GND. However, PL602-37/-39 have SEL0 (pin 10),
and pin11 is VDD. See pin assignment table for details.
Note: On QFN package there is a large center pad for thermal relief.
This pad needs to be connected to GND.
